Azimuthal Anisotropy Measurements in Pb Pb Collisions at p $\sqrt{s_{NN}}$ = 2.76 TeV and Possibility of Finding Jet like Events in PMD

The normal matter that exists around us is made up of atoms and molecules which consist of electrons circling around a nucleus made up of protons and neutrons, the protons and neutrons called nucleons are bound states of quarks and gluons. No free quarks or gluon have been observed in nature. The deep inelastic electron-proton scattering provided the _rst evidence for the internal structure of nucleons, that they were built from quarks and gluons. The quarks and gluons carry color charge. The _eld theory which describes the dynamics of color charged objects and particles undergoing strong interactions is the Quantum Chromodynamics (QCD). QCD predicts that above a critical energy density, _c _1 GeV/fm3 and temperature, Tc _170 MeV, nuclear matter undergoes a transition from normal hadronic state to a decon_ned partonic phase of quarks and gluons called as the quark-gluon plasma (QGP). Such a decon_ned state of quarks and gluons is believed to have existed in the early universe and permeated the entire space a few microseconds after the Big Bang. By colliding heavy-ions, it is believed that such conditions can be created in the laboratory for a eeting instant. Such heavy-ion experiments have been caused out at the Alternating Gradient Synchrotron (BNL), Super Proton Synchrotron (CERN) and Relativistic Heavy Ion Collider (BNL).
