$K^{-}$-Nucleus Scattering at Low and Intermediate Energies

Abstract

We calculate $K^{-}$-nucleus elastic differential, reaction and total cross sections for different nuclei (${}^{12}$C,${}^{40}$Ca and ${}^{208}$Pb) at several laboratory antikaon momenta, ranging from 127 MeV to 800 MeV. We use different antikaon-nucleus optical potentials, some of them fitted to kaonic atom data, and study the sensitivity of the cross sections to the considered antikaon-nucleus dynamics.
