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

Identification of nuclear effects in neutrino and antineutrino interactions on nuclei using generalized final-state correlations

“…As was first proposed and discussed in Refs. [21,57], it enables to extract, on an event-by-event basis, neutrino-and antineutrinohydrogen interactions from compound targets that contain hydrogen atoms. In addition to the double-TKI [21], the single-TKI (imbalance between the charged lepton and hadrons) and p N in principle could also provide separation power between interactions on hydrogen and heavier nuclei when the detector responses are optimized.…”
