# $Z^\prime$s in neutrino scattering at DUNE

## TL;DR

This paper explores how the DUNE experiment can detect new leptophilic neutral currents through neutrino scattering and trident production, potentially addressing anomalies like the muon g-2 discrepancy.

## Contribution

It analyzes the sensitivity of DUNE to anomaly-free $U(1)$ extensions, providing new constraints on $L_e - L_$ and $L_ - L_$ models.

## Key findings

- DUNE can significantly constrain leptophilic $U(1)$ models.
- DUNE's sensitivity covers explanations for the muon g-2 anomaly.
- Neutrino-electron scattering and trident production are effective probes.

## Abstract

Novel leptophilic neutral currents can be tested at upcoming neutrino oscillation experiments using two complementary processes, neutrino trident production and neutrino-electron ($\nu-e$) elastic scattering. Considering generic anomaly-free $U(1)$ extensions of the Standard Model, we discuss the characteristics of $\nu-e$ scattering as well as $e^+e^-$ and $\mu^+\mu^-$ trident production at the DUNE near detector in the presence of such BSM scenarios. We then determine the sensitivity of DUNE in constraining the well-known $L_e - L_\mu$ and $L_\mu - L_\tau$ models. We conclude that DUNE will be able to probe these leptophilic models with unprecedented sensitivity, covering unproved explanations of the $(g-2)_\mu$ discrepancy.
