The s-wave isoscalar amplitude for 7rcr scattering in a nuclear medium is evaluated using a nonperturbative unitary coupled channels method and the standard chiral Lagrangians. The method has proved successful to describe the 7rTr properties in the scalar-isoscalar channel up to 1.2 GeV, giving rise

A recently developed non-perturbative chiral approach to describe the S = -1 meson-baryon reactions has been extended to investigate the near threshold K-p ---, yA,y.~ Β° reactions. With the parameters governed by chiral SU(3) symmetry, we show that the predicted branching ratios I'K-p\_,yA/FK-p~al I
