|Title:||Constraints On Neutrino Decay Lifetime Using Long-baseline Charged And Neutral Current Data|
|Abstract:||We investigate the status of a scenario involving oscillations and decay for charged and neutral current data from the MINOS and T2K experiments. We first present an analysis of charged current neutrino and anti-neutrino data from MINOS in the framework of oscillation with decay and obtain a best fit for non-zero decay parameter α3. The MINOS charged and neutral current data analysis results in the best fit for |δm32 2|=2.34 × 10-3eV2, sin2θ23 = 0.60 and zero decay parameter, which corresponds to the limit for standard oscillations. Our combined MINOS and T2K analysis reports a constraint at the 90% confidence level for the neutrino decay lifetime τ3/m3 > 2.8 × 10-12s/eV. This is the best limit based only on accelerator produced neutrinos.|
