Dr. A.R. Fazely's Research Interest

 

MY AREAS OF INTEREST ARE FUNDAMENTAL INTERACTIONS, TEST OF UNIFICATION THEORIES AND UNDERSTANDING THE NATURE OF THE COSMOS. FOR THESE GOALS, WE RESORT TO EXPERIMENTS. ONE WAY OF ACHIEVING SOME OF THE OBJECTIVES MENTIONED ABOVE, IS TO LOOK AT THE NATURE OF NEUTRINOS. SPECIFICALLY, WE SEARCH FOR NEUTRINO OSCILLATIONS. THIS IS A SPONTANEOUS TRANSMUTATION OF ONE NEUTRINO TYPE TO ANOTHER TYPE. I AM A MEMBER OF THE LIQUID SCINTILLATOR NEUTRINO DETECTOR (LSND) COLLABORATION PRESENTLY OPERATIONAL AT THE LOS ALAMOS NATIONAL LABORATORY MESON PHYSICS FACILITY (LAMPF). THE LSND EXPERIMENT HAS BEEN MAKING HEADLINES IN THE PAST YEAR BECAUSE OF EVIDENCE WE HAVE OBSERVED FOR NEUTRINO OSCILLATIONS* THIS HAS PROFOUND EFFECTS ON OUR UNDERSTANDING OF THE PHYSICS BEYOND THE STANDARD MODEL AND COULD PARTIALLY EXPLAIN THE MISSING MASS OF THE UNIVERSE.

IN COSMIC-RAY ASTROPHYSICS, I AM INVOLVED IN TWO EXPERIMENTS THE FIRST EXPERIMENT CALLED, THE ALPHA MAGNETIC SPECTROMETER, IS A SPACE-BASED DETECTOR TO BE FLOWN ON THE INTERNATIONAL SPACE STATION. THE PRIMARY OBJECTIVE OF THIS EXPERIMENT IS TO SEARCH FOR ANTIMATTER (ANTI-NUCLEI SUCH AS ANTI-HELIUM AND ANTI-CARBON) IN THE UNIVERSE. THIS WOULD ANSWER QUESTIONS REGARDING THE BARYON ASYMMETRY OBSERVED IN THE UNIVERSE. THE OTHER EXPERIMENT IS A HIGH ENERGY COSMIC-RAY BALLOONBORNE EXPERIMENT AIMED AT UNDERSTANDING THE ACCELRATION MECHANISIMS OF PROTONS AND NUCLEI IN OUR UNIVERSE. THE NAME OF THIS DETECTOR IS ADVANCED THIN IONIZATION CALORIMETER (ATIC)* THE ATIC INSTRUMENT IS USED TO MEASURE THE ENERGY OF PROTONS AND HELUIM HUMCLEI FROM 10 CEV TO 100 TEV- THE AIM IS TO ANSWER QUESTIONS REGARDING A SUDDEN FALL OFF IN THE ENERGY SPECTRUM OF PROTONS ABOVE A FEW TEV'S.

THESE EXPERIMENTS, FUNDED BY DOE AND NASA, PROVIDE A UNIFIED APPROACH TO A BETTER UNDERSTADING OF OUR UNIVERSE.
