Abstract

The present talk will be based on kinetics of chiral transitions in quarkmatter that is probably produced resulting from a heavy ion collision.I will focus on far from equilibrium kinetics, subsequent to a quench froma dis ordered phase ( with zero quark condensates) to the ordered phase.This rapid quench renders the system thermodynamically unstable. Theevolution to the new equlibrium state is charecterized by spatio temporalpattern formation,with emergence and growth of domains of the preferred phase. Thisnonlinear evolution is usually referred to as phase ordering dynamics orcoarsening or domain growth.I will discuss the universal properties (e.g. growth laws, scaling ofcorrelation functions, bubble dynamics etc.) in the late stages of chiralkinetics.This will be presented within the Nambu-Jona Lasinio model to describechiral transition in strong interaction physics.

Abstract

On July 4, 2012 two experiments, working at the CERN Large Hadron Collider, jointly announced a strong evidence of observing a new particle state. The observed particle, approximately 135 times heavier than proton and with a very short life time, could be the elusive Higgs boson which the high energy physicists have been earnestly looking for during the past 25 years. This will close one of the puzzles of the Standard Model of particle physics. More recent data have demonstrated some of the intrinsic properties of this new particle. The search involved a consolidated effort from thousands of physicists from all over the world over two decades. The challenges in this search and Indian effort in this process will be discussed.
