✦ Synopsis

Using a simple parametrization of Breit-Wigner type for the hadronic side of the QCD sum rule for p mesons in vacuum as well as in a nuclear medium we explore the range of values for the mass and the width of the p meson, which are compatible with the operator product expansion.

Using QCD sum rules, we compute the diagonal meson-baryon couplings, Ο€NN, Ξ·NN, Ο€ , Ξ· , Ο€ and Ξ· , from the baryon-baryon correlation function with a meson: i d 4 x e iqβ€’x 0|T J B (x) JB (0) |M(p) . The calculations are performed to leading order in p Β΅ by considering the two separate Dirac structures
