Identified charged Hadron production in Au-3He collisons at√ sNN = 200 GeV

Abstract

In this thesis, we have done extraction and study of π ±, K± and p(¯p) from STAR and AMPT data for Au-3He collisions at √ sNN = 200 GeV. We started with event and track QA selection followed by centrality determination for the 200 GeV Au-3He events. Then we proceed to extracting raw yeilds using dE/dx method in STAR TPC and m2 fitting in TOF detector. Observables like average transverse momentum (hpT i), particle yields (dN/dy) and kinetic freeze-out properties are extracted from AMPT-SM data. Kinetic freezeout properties are extracted using hydrodynamics motivated blast-wave model fits to the data . In the appendices, we have discussed the theoretical description of the 3He nucleus using Green’s Function Monte Carlo (GFMC) Method. We have compared AMPT simulations, with and without modified 3He distribution. We see that the Pearson correlator and eccentricities are lower when we use modified 3He nuclear profile. Future plans are also discussed.
