Reconstruction of Energy Spectra of Neutrino Beams Independent of Nuclear Effects: Prospects for Current Experiments

TL;DR

This paper explores a method to accurately reconstruct neutrino energy spectra in the few-GeV range by using neutrino-hydrogen interactions, minimizing nuclear effect uncertainties, and discusses its application prospects in current experiments.

Contribution

It introduces a technique to extract neutrino-hydrogen interactions from multinuclear targets using transverse kinematic imbalance, enabling nuclear-effect-independent energy spectrum reconstruction.

Findings

Neutrino energy spectra can be reconstructed independently of nuclear effects.

Transverse kinematic imbalance is effective for isolating neutrino-hydrogen interactions.

The method shows promising prospects for current neutrino experiments.

Abstract

The energy spectrum of a neutrino beam in the few-GeV region is free of uncertainties from nuclear effects when reconstructed via neutrino-hydrogen interactions. On a multinuclear (hydrogen containing) target such interactions can be extracted using transverse kinematic imbalance. We discuss the prospects of this technique for current experiments.
