dc.description.abstract One of the recent interests in high energy physics is to study the phase diagram of strongly interacting matter.QCD phase diagram has been studied extensively in the temperature (T) - baryon chemical potential (μB) plane [1, 2].The first principle lattice QCD (LQCD) simulations give a reliable prediction about the nature of QCD phases andphase transitions at zero baryon chemical potential and finite temperature [3–5]. Although LQCD calculations can betrusted undoubtedly at small baryon chemical potentialμB'0, at relatively large baryon chemical potential latticecalculations suffer from the “fermion sign problem”[6]. LQCD calculations predict that atμB= 0, the nature ofthe transition from confined hadronic phase to deconfined quark gluon plasma (QGP) phase is not a thermodynamicphase transition rather it is a smooth crossover with a transition temperatureTc∈[149−163] MeV [7]. On theother hand, QCD inspired effective field theory models e.g. Nambu-Jona-Lasinio model (NJL) etc., indicate that thephase transition from the hadronic phase to QGP phase at large baryon chemical potential and small temperatureis first order in nature with physical quark masses. This indicates the presence of a critical endpoint at the end ofthe first order chiral phase transition line in the QCD phase diagram. Apart from the confined hadronic phase anddeconfined QGP phases, QCD phase diagram has a very rich structure at a low temperature and high baryon chemicalpotential. In this region of the phase diagram, possibility of various exotic phases has been investigated such as thecolor superconducting phase[8–10], quarkyonic phase[11], inhomogeneous chiral condensed phase [12–14], etc. en_US
