“…There are tensions between published data from the T2K, MiniBooNE, and MINERvA experiments [1][2][3][4][5]. These tensions exist in the charged current production of both zero and one pion final states, and a model has yet to emerge that can reliably simulate all experiments at once.…”

Faced with unresolved tensions between neutrino interaction measurements at few-GeV neutrino energies, current experiments are forced to accept large systematic uncertainties to cover discrepancies between their data and model predictions. In this paper, the widely used pion production model in GENIE is compared to four MINERvA charged current pion production measurements using NUISANCE. Tunings, i.e., adjustments of model parameters, to help match GENIE to MIN-ERvA and older bubble chamber data are presented here. We find that scattering off nuclear targets as measured in MINERvA is not in good agreement with expectations based upon scattering off nucleon (hydrogen or deuterium) targets in existing bubble chamber data. An additional ad hoc correction for the low-Q 2 region, where collective nuclear effects are expected to be large, is presented. While these tunings and corrections improve the agreement of GENIE with the data, the modeling is imperfect. The development of these tunings within the NUISANCE framework allows for straightforward extensions to other neutrino event generators and models, and allows omitting and including new data sets as they become available.

“…The remaining uncertainties are due to the cross section models for neutrino interactions. The uncertainty on the CC0π cross section in the energy range relevant for these backgrounds is roughly 10% [217]. Based on these two effects, a conservative 20% systematic uncertainty in the background is estimated.…”

“…In the absence of a generally adopted and reliable model for neutrino-nucleus interactions which would be available in a wide energy range, different authors use different phenomenological models tuned to different energy ranges and detector targets. As a result, the values of the fundamental phenomenological parameters for neutrino-nucleon interactions, extracted from the experiments, strongly depend on the interaction model used in analyses, and on average energies of neutrino and antineutrino beams (see, e.g., recent reviews [40,41] and references therein). This in turn leads to uncertainties in extrapolations of the cross section models from one target material to another.…”

Letter of interest for a neutrino beam from Protvino to KM3NeT/ORCA

The Protvino accelerator facility located in the Moscow region, Russia, is in a good position to offer a rich experimental research program in the field of neutrino physics. Of particular interest is the possibility to direct a neutrino beam from Protvino towards the KM3NeT/ORCA detector, which is currently under construction in the Mediterranean Sea 40 km offshore Toulon, France. This proposal is known as P2O. Thanks to its baseline of 2595 km, this experiment would yield an unparalleled sensitivity to matter effects in the Earth, allowing for the determination of the neutrino mass ordering with a high level of certainty after only a few years of running at a modest beam intensity of $$\approx ~90~\hbox {kW}$$≈90kW. With a prolonged exposure ($$\approx 1500\hbox { kW}\,\,\hbox {year}$$≈1500kWyear), a $$2\sigma $$2σ sensitivity to the leptonic CP-violating Dirac phase can be achieved. A second stage of the experiment, comprising a further intensity upgrade of the accelerator complex and a densified version of the ORCA detector (Super-ORCA), would allow for up to a $$6\sigma $$6σ sensitivity to CP violation and a $$10^\circ {-}17^\circ $$10∘-17∘ resolution on the CP phase after 10 years of running with a 450 kW beam, competitive with other planned experiments. The initial composition and energy spectrum of the neutrino beam would need to be monitored by a near detector, to be constructed several hundred meters downstream from the proton beam target. The same neutrino beam and near detector set-up would also allow for neutrino-nucleus cross section measurements to be performed. A short-baseline sterile neutrino search experiment would also be possible.
