Feasibility study of e-µ azimuthal correlation from open heavy flavor in ALICE at LHC energies

Abstract

What are the fundamental particles ? Perhaps answer of this question may be different to di erent person. But the particle physicist may ask at what energy. In earlier time technology was not so advanced that can create very high energy. One needs high energy accelerator to penetrate more and more inside atoms. Last few decades we have really advanced in accelerator science which helps us to discover many fundamental particles in nature. Those particles were predicted by the standard model as well. In this chapter, rst we will discuss about the standard model which is the theory of fundamental forces (except gravitational force) and particles. Next we will introduce Quantum Chromodynamics (QCD) which is the theory of strong interaction as my work is related to the strong force. QGP (Quark Gluon Plasma) which is expected to be formed in the early stages after the big-bang, can be created through heavy ion collisions in the laboratory. So, QGP and di erent observables to know about this state of the matter will be explained next. Heavy avor (charm and bottom) quarks are created in the early stages of the heavy ion collision, can be the carrier of the information about the QGP medium. Finally, in this chapter we will focus on heavy avour mesons and its production processes as my thesis work is based on the open heavy avour mesons.
