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

A series of new physics scenarios predict the existence of the extra charged gauge boson W',which can induce charged-current（CC） non-standard neutrino interactions（NSIs）.The theoretical constraints on the simplified W' model and further on the CC NSI parameters ■ from partial wave unitarity and W' decays are considered.The sensitivity of the process pp→ W'→lv to the W' model at the LHC and high-luminosity（HL） LHC experiments is investigated by estimating the expected constraints on ■（α=β=e or μ） using a Monte-Carlo（MC）simulation.We find that the interference effect plays an important role,and the LHC can strongly constrain ■.Compared with those at the 13 TeV LHC with L=139 fb-1,the expected constraints at the 14TeV LHC with L=3 ab-1 can be strengthened to approximately one order of magnitude.
