Impact of non-standard interactions on neutrino-nucleon scattering

Abstract

Non-standard neutrino-nucleon interaction is formulated and explored within the energy range of quasi-elastic scattering. In particular, the study focuses on the neutral-current elastic (anti)neutrino scattering off nucleons described by the exotic reactions ${\nu }_{\alpha }({\bar{\nu }}_{\alpha })+n\to {\nu }_{\beta }({\bar{\nu }}_{\beta })+n$ and ${\nu }_{\alpha }({\bar{\nu }}_{\alpha })+p\to {\nu }_{\beta }({\bar{\nu }}_{\beta })+p$, which provide corrections to the dominant Standard Model processes. In this context, it is shown that the required exotic nucleon form factors may have a significant impact on the relevant cross sections. Besides cross sections, the event rate is expected to be rather sensitive to the magnitude of the lepton-flavour violating parameters resulting in an excess of events. The overlap of non-standard interactions and strange quark contributions, in the region of few GeV neutrino energies, is also examined. The formalism is applied for the case of the relevant neutrino-nucleon scattering experiments (LSND, MiniBooNE, etc.) and motivates the notion that such facilities have high potential to probe NSI.
