Event rates for nu_e and anti-nu_e appearance oscillations reported by the MINOS and T2K long baseline experiments are used to set constraints on the strength of the non-standard interaction epsilon_{e tau}V_e matter potential. The ranges allowed for the magnitude and phase of epsilon_{e tau} are delineated for scenarios wherein i) other non-standard interactions for neutrinos propagating through the terrestrial crust are negligible, and ii) the real-valued, flavor-diagonal couplings epsilon_{e e} and epsilon_{tau tau} are also operative. Our analysis makes use of accurate analytic forms for the nu_e amplitude A(nu_mu --> nu_e) describing neutrino oscillation in constant-density matter in the presence of epsilon_{e tau}, epsilon_{e e} and epsilon_{tau tau} non- standard interactions.
We report new constraints on flavor-changing non-standard neutrino interactions from the MINOS long-baseline experiment using $ u_{e}$ and $bar{ u}_{e}$ appearance candidate events from predominantly $ u_{mu}$ and $bar{ u}_{mu}$ beams. We used a stat
Given the elusive nature of neutrinos, their self-interaction is particularly difficult to probe. Nevertheless, upper limits on the strength of such an interaction can be set by using data from terrestrial experiments. In this work we focus on additi
Using 1.8 million DDbar pairs and a neutrino reconstruction technique, we have studied the decays D^0 -> K^- e^+ nu_e, D^0 -> pi^- e^+ nu_e, D^+ -> Kbar^0 e^+ nu_e, and D^+ -> pi^0 e^+ nu_e. We find B(D^0 -> pi^- e^+ nu_e) = 0.299(11)(9)%, B(D^+ -> p
Using a sample of 1.8 million DDbar meson pairs collected at the psi(3770) with the CLEO-c detector, we study the semileptonic decays D^0 -> pi^- e^+ nu_e, D^+ -> pi^0 e^+ u_e, D^0 -> K^- e^+ u_e, and D^+ -> Kbar^0 e^+ nu_e. For the total branching
The long baseline neutrino experiments, T2K and NOvA, have taken significant amount of data in each of the four channels: (a) $ u_mu$ disappearance, (b) $bar u_mu$ disappearance (c) $ u_e$ appearance and (d) $bar u_e$ appearance. There is a mild tens
