Neutrino: Dr. Parsa in 1998 started the Neutrino (v) Charge Parity violation (CPV) and extra Long Baseline (L, 1300 km < L < 4000 km) Neutrino (LBN) oscillation Physics and Experiment, (LBNE) that envisioned sending very intense neutrino (ν) beam through the earth to a far away underground multipurpose large detector to search for Physics potentials for making precision measurements of all neutrino oscillation parameters, Proton decay and natural sources of neutrino; such as supernova. Very long distance (baseline) is the key to this approach, and provide possibility of observing multiple nodes of the neutrino oscillation probability in appearance and disappearance experiments. Observation of such a pattern will demonstrate oscillatory nature of the flavor changing phenomenon, LBNE would be capable of measuring high-statistics neutrino signals from a supernova in our galaxy, provide information on inside of newly-formed neutron star, and possible observation of black hole formation. LBNE was high priority fundamental Science project for over a dacade. Funding was approved to start LBNE at BNL, but BNL Director (P. Paul said) returned the money to DOE due to conflict of AGS chair (retired) who wanted more funds etc. In 2012 DOE approved LBNE with source at FNAL; LBNE was renamed DUNE. Member of LBNE, DUNE, LBNF Collaborations.

Ultra-Cold Muons for e.g. precise treatment of brain .. :  Dr. Parsa in 2006, proposed an "Intense Muon Facility" For Multidisciplinary Research. Focus of her LDRD (Lab Director Research and Development) proposal was first to develop an intense source of muons, 10^12 µ± /sec, from the BNL Alternating Gradient Synchrotron, that would span a broad spectrum of disciplines ranging from nano-technology to life sciences and medical diagnostics showing all of which can be researched using muons. And R & D directed toward the conceptual design of the intense muon research facility (that would address muon production, trapping and cooling). A major goal would be (a final focus device capable of) delivering Ultra-Cold Muons with better than nanometer spatial resolution to the experimental areas e.g. Ultra-Cold Muons for precise treatment of brain. Low energy, high intensity and outstanding resolution are the key features of the envisioned facility that allow novel applications, and scientific discoveries complementary to all BNL Facilities.

Muon Collider:   In 1989 Dr. Parsa started the Muon Collider (MC) Physics and Facility research at BNL, that by early 1993 led to "Muon Collider Collaboration" and grew for over a decade. She also was Organizer and Chair of (the biweekly) particle and accelerator physics seminars (1987-1999), and symposia (e.g. on Muon Collider). Muon collider accelerates subatomic particles called muons (μ), and makes them collide, to discover new subatomic forces and particles. Muons are 200 times heavier than electrons; have the same electric charge; interact with matter in the same way; emit less light and lose less energy than electrons when in circular motion; and smaller beamstrahlung. Consequently smaller energy loss and very small energy spread, allow possibility of more particle per bunch and higher luminosity. Higgs boson production also greatly enhanced because the coupling of any Higgs boson is proportional to the mass of the muon.. Multi TeV and small Muon rings for Neutrino Factory (NF) and Higgs Factory were also considered (e.g., the cross section for direct Higgs production from the mu+ mu- collider is 40,000 times that of the e+ e- system). [Muon Collider start with proton accelerator that generate pions (π) from a target; proceeds through phase rotation, (π → μ ν) decay channel; muon cooling; acceleration; storage and then to a detector]. Member of Muon Collider Collab.

Booster:  In 1985 Prof. Parsa joined the U.S. Department of Energy's Brookhaven National Laboratory (BNL), and was invited to the new Booster Task force (to improve on earlier Booster accelerator design etc. that twice had failed the construction funding Reviews..). She "developed analytical formulas" including e.g., Analytical Method For Treatment of Nonlinear Resonances; she used for Booster, SSC, etc., established: the "Booster Technical Notes" series and "compendium of computer codes". Dr. Parsa also was the "Booster Configuration Manager", Editor of the "Booster Design Manual" that she completed, passed the Department of Energy's (DOE) funding Review and BNL Received Booster Construction fundings in 1986. Booster makes it possible for AGS to accelerate Protons and Heavy Ions (HI) and deliver HI up to gold into the Relativistic Heavy Ion Collider. After decades Booster also serves as the energetic heavy ion source for NASA Space Radiation Lab.

SSC:  Dr. Parsa 1986-1993 developed formulations and codes used for the U.S. SSC (Superconducting Super Collider), e.g., her "Second Order Perturbation In SSC";  "Resonance Analysis For The SSC"; "Linear Aperture, Smear, Variation Of Particle Action And Beam Emittance In SSC"; Chromatic Perturbation And Resonance Strength In SSC.. SSC a U.S. Collider under construction in Texas officially demised in 1993.

Neutrino Diagnostics: Dr. Parsa has been Chief Scientist & U.S. Team Leader of the (State Department Funded) Projects with Former Nuclear Weapon Scientists from Russia, Ukraine (1999-2005) etc. E.g, one of her 2004 (STCU) proposal was on "Neutrino Diagnostics of the Fissile Materials in Nuclear Reactor", including antineutrino method of remote control and diagnostics of operating fast neutron reactor. [Antineutrino capture by protons (inverse beta decay) constitutes basis of the detector. By measuring energy of produced positrons, can reconstruct the antineutrino spectra].

Professional Activities:   Professor Parsa in addition to years of Teaching and Research, has been: "Author"; "Referee"; "Editor" and "Editor in Chief" of Newsletters (e.g., APS-NYSS |Vol.3,#1|, |Vol.2,#1|, |Vol.1,#1|); Scientific Papers (e.g., see |Spires Publication|); Manuals and books (e.g., |Intersections of particle and nuclear physics| ); Executive Science International LLC; etc. Member of professional Organizations and Collaborations; has served as Chair, Coordinator, Developer and organizer of Physics Research Programs and Workshops. E.g. Chair and organizer of "New Ideas for Particle Accelerators" Institute for Theoretical Physics, Santa Barbara CA; "Intersection of Particles and Nuclear Physics" New York City, etc. Elected Member of Executive committee of the American Physical Society NY State Section (APSNYSS) (2001-2005); Chairperson and Organizer of APSNYSS Topical Symposium on “Particle Accelerator Frontiers and New Physics Potentials”, BNL; etc. Chairperson of biweekly BNL (Physics) seminars (1987-1999); etc.

Computer Activities: Elected Chair of: Digital Equipment Corporation User Society Upton Section (13 years) and Chair of: BNL Computer Users Group (1986-1999) 13 years; Editor: Computer Codes, Manuals, Computer Primer(s) for VMS, Unix and IBM etc.; Member of Cyber Administration.
