Hadronica
The BCS theory of 3P0 quark-antiquark condensation is given. A method to evaluate overlap kernels is discussed. An introduction to the derivation of Salpeter equations and its relation with RGM equations is presented. The mechanism for the spontaneous breakdown of chiral symmetry and its relation with issues like the pion Goldstne boson, chiral restoration, scalar versus vectorial confinement and hadronic decay are also treated.
