Properties of lightest mesons at finite temperature and quark/baryon chemical potential in instanton model of QCD vacuum

S. V. Molodtsov, A. N. Sissakian, A. S. Sorin +1

The thermal and quark/baryon chemical potential dependences of quark condensate and masses of $\pi$- and $\sigma$-mesons are studied in the instanton model of the QCD vacuum in precritica…
