Determination of CP violation parameter using neutrino pair beam

TL;DR

This paper explores how neutrino pair beams from circulating excited heavy ions can be used in short baseline experiments to detect CP violation and determine neutrino mass hierarchy with minimized matter effects.

Contribution

It introduces a novel approach using neutrino pair beams for measuring CP violation and identifying mass hierarchy in neutrino oscillation experiments.

Findings

Double weak event detection shows high sensitivity to CP violation.

Short baseline experiments reduce earth-induced matter effects.

Method can distinguish different neutrino mass hierarchy patterns.

Abstract

Neutrino oscillation experiments under neutrino pair beam from circulating excited heavy ions are studied. It is found that detection of double weak events has a good sensitivity to measure CP violating parameter and distinguish mass hierarchy patterns in short baseline experiments in which the earth-induced matter effect is minimized.
