Abstract

Neutrinos can pass through substantial matter, potentially enabling direct links where electromagnetic paths are obstructed, but their weak interactions make reception difficult. We present two separate calculations. First, a repeated OOK/CRC simulation calibrated to the published NuMI-MINERvA selected-event mean correctly accepts 65.7% of simulated packets with a 40-bit payload and an eight-bit CRC after five repetitions, with about 587 s mean latency under assumed external synchronization. Varying the input mean across its approximate Poisson counting interval gives 60-72% correct acceptance; this is a sensitivity range, not a joint confidence interval. Second, a distinct idealized far-field model gives 24.4 MW peak neutrino-carried on-slot power for a 10 kt receiver at 5,000 km, conditional on 3 GeV neutrinos, 1 mrad divergence, 50% selection efficiency, unit flavor survival, zero background and one-second slots. Neither result establishes a practical long-baseline source or measured CRC performance.

Construction, commissioning, and performance of the ENUBET demonstrator

A final full-size prototype of the instrumented decay tunnel of ENUBET, referred to as the Demonstrator, was constructed and its performance was tested during the 2022, 2023 and 2024 beam test campaigns at the CERN East Area facility. We demonstrate the full scalability of this specialized longitudinal sampling calorimeter technology, based on iron absorbers and scintillator tiles readout by wavelength-shifting fibers and SiPMs. In addition, we evaluate the channel-by- channel response and the performance in terms of electron energy resolution, linearity, and particle identification capabilities, using charged particle beams with energies up to 5 GeV. A comparison with the predictions of a GEANT4 simulation of the prototype is also presented. The achieved energy resolution ($\sim 17$\% at 1 GeV and 10\% at 3 GeV) fully satisfies the requirements for positron identification. The results meet the requirements for neutrino monitoring through lepton identification in the decay tunnel and validate the ENUBET full simulation. Although some limitations have been identified, they can be readily addressed in future developments.

First Measurement of the Superscaling Variable as a Function of Visible Kinematics in Charged-Current Quasi-Elastic Neutrino--Nucleus Scattering

We report the first measurement of the superscaling variable $ψ^{\prime}_{\rm vis}$ in neutrino--nucleus scattering, using charged-current quasielastic-like $ν_μ$-Carbon interactions collected by the MINERvA experiment in the medium-energy NuMI beam. Originally developed to characterize phenomena of scaling with respect to atomic number and momentum transfer in quasielastic electron-nucleus scattering, $ψ^{\prime}$ is reconstructed here from visible final-state kinematics ($ψ^{\prime}_{\rm vis}$). $ψ^{\prime}_{\rm vis}$ is used here as an externally calibrated variable whose peak position is sensitive to the invisible nuclear missing energy. We measure $ψ^{\prime}_{\rm vis}$ as functions of the hadronic recoil $ΣT_p$ and muon transverse momentum $p_{\text{T}μ}$, comparing background-subtracted data to five neutrino--nucleus interaction models via a forward-folding technique. The predicted $ψ^{\prime}_{\rm vis}$ diverges most strongly among model predictions at low $ΣT_p$ and $p_{\text{T}μ}$, where agreement with data is also poorest, exposing which models fail to capture the phase-space dependence of the missing energy and therefore the neutrino energy as extrapolated from visible kinematics. Among tested models, we find that the Relativistic Mean Field approach predicts more accurately the $ψ^{\prime}_{\rm vis}$ peak position.

Natural Chlorine Enhances Antineutrino Detection in the Deep Ocean

Large-volume neutrino telescopes such as IceCube and KM3NeT exploit natural ice or water as detection media, but their sparse instrumentation makes MeV neutrino interactions difficult to identify individually. We show that chlorine naturally abundant in seawater provides an intrinsic neutron-capture target that enables efficient tagging of electron antineutrinos through inverse beta decay. In contrast to the 2.2 MeV $γ$-ray from neutron capture on hydrogen, capture on chlorine produces an $\sim$8.6 MeV $γ$-ray cascade on a shorter time scale, yielding a distinctive delayed-coincidence signature. Using measured seawater properties at the TRIDENT site and a detector-level simulation, we find that chlorine-assisted tagging can extend the core-collapse supernova 5$σ$ discovery reach from $\sim$50 to over 100 kpc. We validate the underlying detection principle with a salted-water experiment at the China Jinping Underground Laboratory, observing correlated neutron-capture signatures under suppressed cosmic muon background conditions. Natural seawater thus transforms the deep ocean into an intrinsically enhanced antineutrino detection medium, opening new opportunities for MeV neutrino astronomy and distributed measurements of reactor and geophysical antineutrinos.
