We analyze chiral restoration within the O(N + 1)/ O(N) nonlinear sigma model for large N as an effective theory for low-energy QCD at finite temperature T. The free energy is constructed diagrammatically to O(TM^3) in the pion mass expansion, w[...]texto impreso
Gómez Nicola, Ángel ; Cortés, Santiago ; Morales, John ; Ruiz de Elvira Carrascal, Jacobo ; Torres Andrés, Ricardo | E D P Sciences | 2017We discuss recent advances on QCD chiral symmetry restoration at finite temperature, within the theoretical framework of Effective Theories. U(3) Ward Identities are derived between pseudoscalar susceptibilities and quark condensates, allowing t[...]texto impreso
We consider the O(N + 1)/O(N) nonlinear sigma model for large N as an effective theory for low-energy QCD at finite temperature T, in the chiral limit. At T = 0 this formulation provides a good description of scattering data in the scalar channe[...]texto impreso
