WITHDRAWN: Neutrinos and their interactions with matter

The µ–τ reflection symmetry of Majorana neutrinos *

“…An unambiguous determination of the octant of θ 23 and more stringent tests of the unitarity of the 3 × 3 PMNS matrix U are our important targets too. Meanwhile, a number of non-oscillation experiments are underway towards probing the Majorana nature of massive neutrinos and determining the absolute neutrino mass scale [322].…”

“…It turns out that both the relationship M ν = PM * ν P and the conditions in equation (7.35) can be satisfied, and therefore H eff = PH * eff P holds even in the presence of NSIs. At this point it is worth mentioning that the interesting relation ϵ eµ = tan θ 23 ϵ eτ , which comes from a purely phenomenological observation [321] but happens to be satisfied in the µ-τ reflection symmetry limit (namely, ϵ eµ = ϵ * eτ and θ 23 = π/4), will efficiently reduce the parameter redundancy associated with neutrino oscillations [321] and thus enhance the experimental testability of possible NSIs in the upcoming long-baseline experiments [322].…”

Snowmass Neutrino Frontier Report

“…Various processes, including quasi-elastic scattering, multi-nucleon knockout, resonance production, and both shallow-and deep-inelastic scattering play important roles at medium neutrino energies [87][88][89]. The neutrinos generated by accelerators and atmospheric sources have a broad energy spectrum.…”

Review of sterile neutrino searches at very short-baseline reactor experiments

“…) the probabilities of neutrino flavor changes from α to β are often well approximated by a two-neutrino formula(see e.g. [15])…”

“…The standard cosmological model strongly disfavors the eV-scale sterile neutrinos (see e.g. [15]). However there are models which include eV-scale sterile neutrinos and reduce the tension between different determinations of the Hubble constant [81].…”
