Neutrino Physics & Experiment
1. Past History
Neutrino physics has had an interesting history. In 1930 Dr.
Pauli postulated the existence of the (electron) neutrino, in
1956 this was confirmed by Drs.
Reines and Cowan using a nuclear
reactor source of antineutrinos. In 1962, a second
distinct (muon) neutrino was shown to exist in a BNL experiment. For
that discovery Nobel Prize was awarded to Drs.
Lederman,
Schwartz and Steinberger. In 1995, the third, (tau) neutrino was
detected at FNAL. In parallel, Dr. Ray Davis' studies of solar
neutrinos confirmed understanding of stellar dynamics modulo
a 2/3 flux deficit that later was recognized as a result of
ν oscillations among the three flavors of neutrinos.
Properties of those oscillations were further unveiled with
followup solar, atmospheric, reactor and accelerator neutrino
studies. The discovery of oscillations, detection of
19 neutrino events from supernova 1987a by the old IMB and
Kamiokande water cherenkov detectors confirmed the theory of
supernova explosions. The WMAP experiment has started to see
imprints of neutrino mass effects on cosmic microwave
back ground radiation left from the Big Bang.
2. Introduction
In 1998 Dr. Zohreh
Parsa started the Neutrino CP Violation studies, extra
Long Baseline (L, 2000 km < L < 4000
km) Neutrino (LBN) oscillation Physics and Experiment (LBNE)
that envisioned sending a very intense neutrino
(ν) beam (e.g., from Brookhaven National Laboratory on Long Island,
New York), through the earth to a far away underground multipurpose
large detector capable of making precision measurements of all the (ν)
neutrino oscillation parameters, Proton decay and observation of
natural sources of neutrinos such as supernova, providing a major
advances in neutrino science. The key to this approach is (extra
long) very long distance L. Length of the Baseline defines the physics
you can do, once chosen, can not be changed without establishing a new
facility.
Extra Long Base lines provide possibility of observing multiple nodes of the
Neutrino oscillation probability in appearance and disappearance
experiments.
By measuring muon neutrino disappearance and electron neutrino
appearance, such a project would be capable of determining all 3
generation mixing angles, mass hierarchy, along with magnitude of the
CP violation (e.g., by measuring CKM phase and explicitly observing
differences in the muon neutrino and muon anti-neutrino
oscillations). No existing experiment so far has such capability.
E.g., Neutrinos emitted in the first few seconds of a core-collapse
supernova, would have insight into evolution of the universe. LBNE
(very Long Baseline Neutrino Experiment), would be capable of
measuring, (collecting and analyzing), the high-statistics neutrino
signals from a supernova in our galaxy; provide information on the
inside of the newly-formed neutron star; allowing possible observation
of black hole creation.
"Very" or "Extra" Long Baseline terms has been used, to distinct our
very Long Baseline (L) from other existing/ or
proposed experiments that use the term "Long Baseline Neutrino
Experiment (LBNE)" but have a short baseline, (e.g. Japan's Super-k
Detector with baseline of less than 300 km, etc). In existing
experiments, Detector(s) were placed
at the first node of oscillations (with short baseline). But with
extra long baseline LBNE, Detector(s) can be placed e.g. at the 2nd or
third nodes of oscillations, that would allow the CP violation
measurement in addition to the mixing angles, etc. In some of our earlier
simulation(s), L (lower bound) was reduced from 2000 km to 1300 km to
correspond to baseline of FNAL to Homestake.
2.1. Neutrinos
Neutrinos are neutral subatomic particles that rarely interact with
matter. Over trillion neutrinos pass through your bodies per second
without leaving a trace. Neutrinos have low masses compared to other elementary
particles. These tiny particles with no electric charge are able to
oscillate, and change from one type of neutrino to
another, when studied at LBNE (DUNE) could provide a deeper understanding
of our universe.
Neutrinos come in three states, or flavors, and can transform from one
flavor into another; and that each neutrino flavor state is a mixture
of three different nonzero mass states. Neutrinos come from nuclear
reactions in stars, our sun, and on Earth. Three flavors are:
electron, Muon and tau Neutrinos, where muon is 200 times heavier than
the electron and tau is 3,500 times heavier.
Neutrinos emitted in the first few seconds of a core-collapse
supernova carry the potential for insight into the evolution of the
universe.
Results from the experiment should enable a broad exploration of the
three-flavor model of neutrino physics, help understand matter-antimatter
asymmetries (through charge-parity symmetry violation (CPV)) in
neutrino flavor mixing; unravel the mystery of matter generation in
the early universe; neutrino mass ordering; and precise measurement
of neutrino mixing parameters. Grand unified theories (GUTs),
predict rates for proton decay that cover a range directly
accessible with the next generation of large underground detectors.
3. LBNE (very Long Baseline Neutrino Experiment)
with Neutrino Source at BNL
Using a wide band muon neutrino beam from BNL to an
underground (e.g., 0.5 megaton water Cherenkov) detector at Homestake gold Mine in
South Dakota was one of our first study for "very Long Baseline
Neutrino Experiment" (LBNE). Interest in
LBNE with neutrino source at BNL to a far away (L=2540 km), underground Detector at Homestake,
grew. Dr. A. Mann (U.Penn.) was one of the 1st to ask Dr. Parsa, (with
his calls and in person), for her results for sending neutrinos (neutrino beam)
from BNL (AGS) to the underground detector(s) in Homestake Gold Mine. He and others became increasingly interested; worked hard to get fundings for water removal and
for Processing the Mine to an Underground Science Lab ("NUSL"; "DUSEL" etc.). Examples of Earlier simulations given in Fig.1 & Fig.2:

distance from ν source to the detector, in Probability vs Energy
plots.

Probability vs Energy plots.
This page include part of Dr. Parsa's
collaborative work.
In addition to Dr. Parsa, later Dr. Marciano (BNL),
and at Snowmass meeting (experimentalists) Drs. K. McDonald (Princeton U.),
S. Kahn (BNL), and
others joined the proposed (Extra) Very "Long Baseline Neutrino
Experiment" (LBNE), that could search for CP violation in the lepton
sector and precision studies of the neutrino mixing matrix and
more. Years later, a BNL associate director (at that time) formed
a group to look into AGS, neutrino source at BNL etc... With time the LBNE
Collaboration expanded to an international collaboration
and LBNE to a mega-science project.

Potentials of intense neutrino beams from BNL and FNAL to (Long Baseline)
underground Detectors at Homestake, SD; Henderson, CO; Cascades,
WA; etc., were also investigated and studied as competition for Deep
Underground Science and Engineering Laboratory Site
increased. Later Homestake, S.D. was selected.

Interest for LBNE in U.S. with neutrino source at BNL to a far Detector
(underground at the Homestake, S.D L=2540 km), grew to fundamental
high priority international mega-science project for over a decade, as
"LBNE Collaboration" continued to expand. According to BNL Director at the
time, BNL received funding from DOE to start the LBNE with Source at
BNL, but (P. Paul said) he "had to return the money back to DOE" due to
conflict of AGS chair (retired) who wanted more funding...
3.1. Neutrino Detector
Neutrino detector is an aparatus/ structure used to detect and study neutrinos.
Since neutrinos interact weakly with other particles, Neutrino
detectors are made very large to detect a large number of neutrinos.
To block the background radiation and cosmic rays, they are placed underground.
There are various detectors (See Top Links- e.g. "Detectors-Photos"),
including: Super Kamiokande a large
volume of water surrounded by phototubes that look for the Cherenkov
radiation emitted when an incoming neutrino generates an electron or
muon in the water; Sudbury Neutrino Detector uses heavy water as
the detecting medium.
Other detectors may have large volumes of chlorine or gallium
that are periodically checked for excesses of argon or germanium,
respectively, which are created by neutrinos interacting with the
original material.
MINOS uses a solid plastic scintillator surrounded by phototubes;
Borexino uses a liquid pseudocumene scintillator also surrounded by phototubes;
The Daya Bay Reactor Neutrino Detector walls are lined with
photomultiplier tubes (PMTs), the tubes are designed to amplify and
record flashes of light that signify an antineutrino interaction.
The acoustic detection of neutrinos is done by
ANTARES, IceCube, and KM3NeT collaborations; etc.
4. LBNE Reconfiguration
Following sections include a brief chronology of LBNE Reconfiguration
with Neutrino Source at FNAL, (The Deep Underground Neutrino
Experiment), DUNE/LBNF development(s) etc. "Left Tabs" provides more
on LBNE and for beam to Detector at SURF (DUNE/LBNE); also on Reactor Experiment; Solar Neutrino Experiment; etc.
In 2012, Fermilab (FNAL) proposed for the LBNE with source at
FNAL. Phase-I (CD-1) was approved by DOE which
included construction of a Neutrino beamline
at FNAL, where the Neutrino beam would travel through
earth to a far detector at Sanford Lab in
Lead, S.D.
|Click Here|. For Brookhaven National Laboratory, DOE's approval of CD-1 was an
important milestone after over decade of LBNE work at BNL.
Using a high intensity accelerator neutrino beam from FNAL to a, (L=1287.475 km or about 800 miles baseline) liquid Argon TPC detector at SURF
(Homestake), is the LBNE reconfiguration. This program goals, (are the BNL LBNE physics
goals that started over a decade earlier), include Determination of leptonic CP violation, v
mass hierarchy, underground physics etc. LBNE with source at FNAL later was renamed Deep
Underground Neutrino Experiment (DUNE). LBNE Collaboration became DUNE
Collaboration.

5. DUNE/ LBNF 
The Deep Underground Neutrino Experiment (DUNE) expected to use the most intense
neutrino beam and a larg detector to study neutrino (v) the most
abundant matter particles in the universe. Scientists continue
working to discover the missing pieces that could explain e.g., how the known particles
and forces created in our universe; discover if neutrino is the
reason our matter-filled universe exists, to check formation of
black hole in a nearby galaxy; proton decay, etc.
The full-size DUNE Detector, expected to be built about a mile
underground at the Sanford Research Facility (in homestake, South
Dakota). Detectors record particle tracks emerging from
rare neutrino collisions with (massive target material) atoms. For

November 14, 2019 -- Over the next few years
Fermilab is to build a new beamline for its accelerator complex to

detector (1300 Km away) in South Dakota. |Here|
Without neutrinos from Fermilab and with DUNE detector(s) in place, only a
long baseline neutrino beam e.g. from BNL (with AGS upgrade after few years) directed to South Dokota
allow scientists to investigate the neutrinos and their role in the
evolution of our universe: e.g., the neutrinos interact as they
travel long distances; the differences between neutrinos and their
antimatter which can provide clues why we are made of matter not
antimatter; the neutrinos produced when a star explodes could reveal
the formation of neutron stars and black holes; and protons lifetime
(wether they live forever or eventually decay).

based on this prototype, but 20 times larger. We are happy with the 1st
physics results published; as some of our DUNE members (from BNL) delivered
Components for the Proto-DUNE Detector. E. Worcester, BNL said “the
ProtoDUNE results show that we have designed a detector that
will allow us to reach our science goals in DUNE"; etc. This first DUNE
paper, show how they were able to achieve a signal-to-noise
ratio of 50 to 1, which previously could not achieve for liquid-argon time
projection chambers. They also evaluated detector’s reliability and found
more than 99% of its 15,360 detector channels are functioning as they
