Constraining the transitional magnetic dipole moment interaction between active and heavy neutrinos with the [Formula omitted] at FASER[Formula omitted]

We investigate the effects of the transitional magnetic dipole type interactions of the active-to-heavy-neutrino associated with a new neutral gauge boson [Formula omitted] on neutrino-nucleon scattering at the ForwArd Search ExpeRiment- [Formula omitted] (FASER [Formula omitted]). We consider the n...

Description
Summary:We investigate the effects of the transitional magnetic dipole type interactions of the active-to-heavy-neutrino associated with a new neutral gauge boson [Formula omitted] on neutrino-nucleon scattering at the ForwArd Search ExpeRiment- [Formula omitted] (FASER [Formula omitted]). We consider the neutral-current neutrino-nucleon scattering ( [Formula omitted], where [Formula omitted] denotes the disintegrated nuclei) as the production mechanism of the heavy neutrino N at FASER [Formula omitted] and estimate the sensitivity reach on the magnetic-type dipole coupling [Formula omitted] for a range of heavy neutrino mass ( [Formula omitted]). In this study, we consider three benchmark models, in which the heavy neutrino is coupled to [Formula omitted], [Formula omitted] or [Formula omitted] doublet, respectively.
