Probing the sensitivity to leptonic \(\delta_{CP}\) in presence of invisible decay of \(\nu_3\) using atmospheric neutrinos
One of the main neutrino oscillation parameters whose value has not been determined very precisely is the leptonic \(\delta_{CP}\) phase. Since neutrinos have a tiny but finite mass they can undergo decay both visibly and invisibly. The effect of invisible decay of the third mass eigen state \(\nu_3...

description | One of the main neutrino oscillation parameters whose value has not been determined very precisely is the leptonic \(\delta_{CP}\) phase. Since neutrinos have a tiny but finite mass they can undergo decay both visibly and invisibly. The effect of invisible decay of the third mass eigen state \(\nu_3\) on the sensitivity to \(\delta_{CP}\) is analysed here using atmospheric neutrino and anti-neutrino events. Effects of detector resolutions and systematic uncertainties are studied to identify the optimum resolutions and efficiencies required by a detector to obtain a significant sensitivity even in presence of decay. |
