Abstract
Monoenergetic muon neutrinos at 236 MeV are readily produced in intense medium-energy proton facilities (greater than or similar to 2-3 GeV) when a positive kaon decays at rest (KDAR; K+ -> mu(+) nu(mu)). These neutrinos provide a unique opportunity to both study the neutrino interaction and probe the nucleus with a monoenergetic weak-interactiononly tool. We present cross-section calculations for quasielastic scattering of these 236-MeV neutrinos off C-12 and Ar-40, paying special attention to low-energy aspects of the scattering process. Our model takes the description of the nucleus in a mean-field approach as the starting point, where we solve Hartree-Fock equations using a Skyrme type nucleon-nucleon interaction. Thereby, we introduce long-range nuclear correlations by means of a continuum random-phase approximation (CRPA) framework where we solve the CRPA equations using a Green's function method. The model successfully describes (e, e') data on C-12 and Ca-40 in the kinematic region that overlaps with the KDAR nu(mu) phase space. In addition to these results, we present future prospects for precision KDAR cross-section measurements and applications of our calculations in current and future experiments that will utilize these neutrinos.
