We investigate the status of a scenario involving oscillations and decay for charged neutral current data from MINOS T2K experiments. first present an analysis neutrino anti-neutrino in framework oscillation with obtain best fit non-zero parameter α3. The results |Δm322|=2.34×10−3eV2, sin2θ23=0.60 zero parameter, which corresponds to limit standard oscillations. Our combined reports constraint at 90% confidence level lifetime τ3/m3>2.8×10−12s/eV. This is based only on accelerator produced neutrinos.
A bstract We investigate the effect of quantum decoherence and relaxation in neutrino oscillations using MINOS T2K data. The formalism open systems is used to describe interaction a system with environment, where strength regulated by parameter Γ. assume an energy dependence parameterized Γ = γ 0 ( E /GeV) n , −2, 0, +2, consider three different scenarios, allowing investigation constraining solar atmospheric sectors same parameter. data present complementary behavior, regard our theoretical...
A bstract We investigate the present constraints from MINOS and T2K experiments for neutrino decay scenario induced by non-diagonal couplings of Majorons to neutrinos. As novelty, on top typical invisible prescription, we add contribution visible decay, where final products can be observed. This new effect depends nature neutrino-Majoron coupling, which scalar or pseudoscalar type. Using combination disappearance data appearance T2K, normal ordering, constrain parameter α ≡ E Γ heaviest...
We investigate the effect of quantum decoherence and relaxation in neutrino oscillations using MINOS T2K data. The formalism open systems is used to describe interaction a system with environment, where strength regulated by parameter $\Gamma$. assume an energy dependence parameterized $\Gamma = \gamma_0 (E/\mbox{GeV})^n$, $n=-2,0,+2$, consider three different scenarios, allowing investigation constraining solar atmospheric sectors same parameter. data present complementary behavior, regard...
