Weak coherent kaon production

We have investigated the coherent production of (anti)kaons in (anti)neutrino-nucleus scattering in the energy range of current neutrino experiments. At the nucleon level, the model incorporates the most important mechanisms allowed by chiral symmetry at lower orders. The treatment of the nucleus is based on the Local Fermi Gas. Kaon distortion is also taken into account by solving the Klein-Gordon equation with realistic optical potentials. Angular and momentum distributions are studied, as well as the energy and nuclear dependence of the total cross section.
