Probing CP violation in the neutrino sector with magic baseline experiments

TL;DR

This paper explores how the magic baseline experiment can detect CP violation in the neutrino sector, potentially observing effects up to several percent within a specific energy range, despite the small predicted CP violation.

Contribution

It demonstrates the potential of the CERN-INO magic baseline experiment to observe CP violation in neutrinos, which was previously difficult due to tiny neutrino masses.

Findings

CP violation can be observed up to several percent.

Magic baseline enhances sensitivity to CP violation.

Energy range of 1-10 GeV is optimal for detection.

Abstract

We investigate the effect of CP violation in the leptonic sector. Due to the tiny neutrino masses its value is predicted to be very small and it is far beyond the experimental reach of the current experiments. Recently, the magic baseline experiment from CERN to INO (Indian Neutrino Observatory) with L=7152 km has been proposed to get a sensitive limit on $\sin \theta_{13}$. We show that due to such magic baseline neutrino beam it is possible to observe CP violation in the neutrino sector upto several percent for the beam energy between (1-10) GeV.
