We calculate cross sections of the reaction channels <(nu)over bar>(e(mu)) --> e(+) (mu(+)) + K- and <(nu)over bar>(e(mu)) + p --> Lambda + e(+) (mu(+)) and investigate their sensitivity to the medium effects. In particular, we consider effects induced by the presence of a low-energy excitation mode in the K-spectrum, associated with correlated Lambda-particle and proton-hole states, and by renormalization of the weak interaction in medium. In order to avoid double counting, various contributions to antineutrino scattering are classified with the help of the optical theorem, formulated within the nonequilibrium Green's function technique.
