TL;DR: In this paper, the rates relative to the corresponding charged current processes are evaluated for events induced by neutral particles and producing hadrons, but no muon or electron, have been observed in the CERN neutrino experiment.
TL;DR: In this paper, the parity broken solution is shown to be an absolute minimum of the potential in SU(2)L × SU( 2)R × U(1) based left-right symmetric gauge theory.
TL;DR: In this paper, the authors construct unified models of weak and electromagnetic interactions using just three gauge fields which correspond to the intermediate vector boson and the photon, and do not predict processes involving neutral lepton currents.
Abstract: We construct unified models of weak and electromagnetic interactions using just three gauge fields which correspond to the intermediate vector boson and the photon. These models may be renormalizable, and do not predict processes involving neutral lepton currents.
TL;DR: In this paper, the standard model expectations for the rare radiative decays B->K^* gamma, B->rho gamma and B-> omega gamma at the next-to-leading order (NLO) were provided.
Abstract: We provide Standard Model expectations for the rare radiative decays B->K^* gamma, B->rho gamma and B-> omega gamma, and the electroweak penguin decays B->K^* l^+ l^- and B->rho l^+ l^- at the next-to-leading order (NLO), extending our previous results to b->d transitions. We consider branching fractions, isospin asymmetries and direct CP asymmetries. For the electroweak penguin decays, the lepton-invariant mass spectrum and forward-backward asymmetry is also included. Radiative and electroweak penguin transitions in b->d are mainly interesting in the search for new flavour-changing neutral current interactions, but in addition the B->rho gamma decays provide constraints on the CKM parameters (\bar\rho,\bar\eta). The potential impact of these constraints is discussed.
TL;DR: In this article, a Monte Carlo event generator simulating neutral and charged current ep interactions at HERA energies and beyond is described, and the present version 4.0 of the generator optionally treats the ep scattering either by means of structure-function parametrizations or on the basis of parton distribution functions in the framework of the quark-parton model.
