sensitivity to low-mass wimps. opera experiment was designed to investigate muon to tau neutrino oscillations in appearance mode. in the decay of the higgs boson into two photons, the unconverted final state photons are not detected in the tracker, so the determination of the associated primary vertex is not trivial. they are related in an exact way to elements of the quark mixing matrix due to an underlying flavoured u(1)′ gauge symmetry, rendering these models particularly predictive. neutrino oscillation patterns are observed at the super-kamiokande detector, which is located 295 km away from the neutrino production point at an angular offset of 2.-independent analysis of$d^{0} \to k_{s}^{0}\pi^{+}\pi^{-}$decays, and. fortunately, ab initio nuclear-structure theory, based on
