Charged lepton induced one kaon production off the nucleon

Abstract

We study single kaon production off the nucleon induced by electrons (positrons) i.e., ${e}^{\ensuremath{-}}({e}^{+})+N\ensuremath{\rightarrow}{\ensuremath{\nu}}_{e}({\overline{\ensuremath{\nu}}}_{e})+\overline{K}(K)+{N}^{\ensuremath{'}}$ at low energies. The possibility of observing these processes with the high luminosity beams available at TJNAF and Mainz is discussed, taking into account that the strangeness conserving electromagnetic reactions have a higher energy threshold for $\overline{K}$ ($K$) production. The calculations are done using a microscopic model that starts from the SU(3) chiral Lagrangians and includes background terms and the resonant mechanisms associated to the lowest lying resonance ${\ensuremath{\Sigma}}^{*}(1385)$.
