Charged-current non-standard neutrino interactions at the LHC and HL-LHC

Abstract

A series of new physics scenarios predict the existence of the extra charged gauge boson $W^{\prime }$, which can induce charged-current (CC) non-standard neutrino interactions (NSIs). The theoretical constraints on the simplified $W^{\prime }$ model and further on the CC NSI parameters ${\tilde{\epsilon }}_{\alpha \beta }^{q{q}^{\prime }Y}$ from partial wave unitarity and $W^{\prime }$ decays are considered. The sensitivity of the process $pp\to W^{\prime }\to \ell \nu$ to the $W^{\prime }$ model at the LHC and high-luminosity~(HL) LHC experiments is investigated by estimating the expected constraints on ${\tilde{\epsilon }}_{\alpha \beta }^{q{q}^{\prime }Y}$ ($\alpha =\beta =e$ or $\mu$) using a Monte-Carlo~(MC) simulation. We find that the interference effect plays an important role, and the LHC can strongly constrain ${\tilde{\epsilon }}_{\alpha \beta }^{q{q}^{\prime }L}$. Compared with those at the $13\mathrm{TeV}$ LHC with $\mathcal{L}=139{\mathrm{fb}}^{-1}$, the expected constraints at the $14\mathrm{TeV}$ LHC with $\mathcal{L}=3{\mathrm{ab}}^{-1}$ can be strengthened to approximately one order of magnitude.
