Search for trilepton nucleon decay via p→e+νν and p→μ+νν in the Super-Kamiokande experiment.

چکیده
The trilepton nucleon decay modes p→e+νν and p→μ+νν violate |Δ(B-L)| by two units. Using data from a 273.4 kt yr exposure of Super-Kamiokande a search for these decays yields a fit consistent with no signal. Accordingly, lower limits on the partial lifetimes of τp→e+νν>1.7×10(32) years and τp→μ+νν>2.2×10(32) years at a 90% confidence level are obtained. These limits can constrain Grand Unified Theories which allow for such processes.

J an 1 99 7 E 787 : A Search for the Rare Decay K + → π + νν Steve
Recent results from the first phase of the E787 experiment and an update on the current status are presented. From the first phase the limit on the K + → π + νν branching ratio is BR(K + → π + νν) < 2.4 × 10 −9. An observation of the decay K + → π + µ + µ − has been made using two separate techniques. An observation of the decay K + → π + γγ has been made and the distribution of two photon inva...
متن کاملStandard Model Tests at the NA62 CERN Experiment
The physics program of the NA62 experiment aims to search for phenomena beyond the Standard Model by measuring the ratio RK = Γ(K→eνe(γ)) Γ(K→μνμ (γ)) and studying the ultra rare decay K + → π+νν . The status of the RK analysis based on ∼ 40% of the data collected during 2007 and 2008 is summarized and the proposed detector layout to measure the branching ratio of the K+ → π+νν decay is described.
متن کاملA Search for B + → K + νν with BABAR
The study of flavor-changing neutral current decays is of fundamental interest. They provide a sensitive window in which to search for possible new physics effects beyond the Standard Model of particle physics. Measurements of these processes at rates significantly above the Standard Model would point, unambiguously, to new physics. One such decay of interest is B+ → K+νν . Herein, we discuss t...
متن کاملDecays from Experiment E787
This paper presents the latest results from experiment E787, at Brookhaven National Laboratory, on K + → π + νν and radiative K + decays. The result for K + → π + νν uses data collected in runs taken during 1995, 1996 and 1997. In addition, we discuss plans for future measurements of K + → π + νν. This decay mode is a very clean probe of the dynamics of the Cabbibo-Kobayashi-Maskawa (CKM) mixin...

We study processes in which neutrinos can be generated as a possible source for the neutrion emission form neutron stars. In the high energy limit and in the range em< E< Mw the cross sention for ye→evv is analytically calculated. We also calculate the cross section for yy→vv in the noncommutative space. The obtained results in comparison with the cross section for yy→vv and yy→ yvv in the...
