Quark and Gluon Condensates in Strongly Magnetized Nuclear Matter

Abstract

Medium modification of the quark and gluon condensates in the strongly magnetized symmetric nuclear medium has been calculated using chiral SU(3) model. The explicit symmetry breaking term and the broken scale invariance part of Lagrangian density of the model are exploited to express the quark and gluon condensates in terms of \(\sigma \), \(\zeta \), \(\delta \), and \(\chi \) fields. The density and temperature dependence of these scalar fields, for different magnetic field strength, are evaluated first and subsequently used as input in the expressions of quark and gluon condensates. Our present study on medium modification of quark and gluon condensates can be used further as input in different QCD sum rules. Consequently, this may help to understand the experimental observables arising from various heavy-ion collision experiments whose one of the aim is to explore the in-medium properties of hadrons.
