Basic oscillation measurables in the neutrino pair beam

TL;DR

This paper demonstrates that neutrino pair beams exhibit oscillating signals from vector currents, enabling precise CP violation measurements and mass hierarchy determination, unlike axial-vector contributions.

Contribution

It introduces the detection of oscillating components from vector currents in neutrino pair beams, offering new avenues for high-precision neutrino oscillation studies.

Findings

Vector current interactions produce oscillating signals in neutrino pair beams.

Axial-vector contributions do not produce such oscillations.

Potential for high-precision CP violation and mass hierarchy measurements.

Abstract

It is shown that the vector current contribution of neutrino interaction with electrons in ion gives rise to oscillating component, which is absent for the axial-vector contribution, when a single neutrino is detected in the recently proposed neutrino pair beam. CP violation measurements are thus possible with high precision along with determination of mass hierarchical patterns.
