We have studied the muon neutrino and antineutrino quasi-elastic (QEL) scattering reactions (ν μ n→μ − p $\bar{\nu }_{\mu}p\to\mu^{+}n$ ) using a set of experimental data collected by NOMAD Collaboration. performed measurements cross-section these processes on nuclear target (mainly carbon) normalizing it to total ν ( $\bar{\nu}_{\mu}$ charged-current cross section. The results for flux-averaged QEL sections in (anti)neutrino energy interval 3–100 GeV are $\langle...

We present the results of a search for νμ→νe oscillations in NOMAD experiment at CERN. The looked appearance νe predominantly νμ wide-band neutrino beam CERN SPS. No evidence was found. 90% confidence limits obtained are Δm2<0.4 eV2 maximal mixing and sin2(2θ)<1.4×10−3 large Δm2. This result excludes LSND allowed region oscillation parameters with Δm2≳10 eV2.

The significance this is its precision, $\pm 4$% 10$ GeV, and 2.6$% $10 GeV regions, where significant uncertainties previous experiments still exist, importance to proposed long baseline oscillation experiments.

Belle II is an experiment operating at the intensity frontier. Over next decades, it will record decay of billions bottom mesons, charm hadrons, and tau leptons produced in 10 GeV electron-positron collisions SuperKEKB high-luminosity collider KEK. These data, collected low-background kinematically known conditions, allow us to measure hundreds parameters that test standard model (SM) probe for existence new particles, mass scales orders magnitudes higher than those studied energy We project...

We describe the planned near-term and potential longer-term upgrades of Belle II detector at SuperKEKB electron-positron collider operating KEK laboratory in Tsukuba, Japan. These will allow increasingly sensitive searches for possible new physics beyond Standard Model flavor, tau, electroweak dark sector that are both complementary to competitive with LHC other experiments.

NOMAD is a neutrino oscillation experiment designed to search for ντ appearance in the CERN-SPS wide band νμ beam. Signal detection relies on identification of charged current interactions using kinematic criteria. The analysis 1995 data sample yields no signal. Combining all studied τ decay modes, limit sin22θμτ<4.2×10−3 obtained large Δm2 at 90% confidence level.
