In-medium effects on chiral condensate through holography

Abstract

The behavior of chiral condensate in a hot and dense medium is investigated within a phenomenological approach inspired by the AdS/CFT correspondence. We find that it decreases when temperature and/or chemical potential are increased, and it vanishes at some critical values. The locus of such critical points is also drawn and discussed.Comment: Contribution to the conference QCD@Work - International Workshop on QCD - Theory and Experiment, 18-21 June 2012, Lecce - Italy 5 pages, 3 figure
