Self-consistent treatment of the quark condensate and hadrons in nuclear matter

E. G. Drukarev, M. G. Ryskin, V. A. Sadovnikova

We calculate the contribution of pions to the $\bar{q}q$-expectation value $\kappa (\rho )=<M|\bar{q}q|M>$ in symmetric nuclear matter. We employ exact pion propagator renormalized by nucleon…
