    Fields with continuously distributed mass

    We describe local field theories with continuously distributed mass. Such models can be realized as models in d > 4 space-time with Poincare invariance only in four-dimensional space-time. We also discuss some po...

    Sleptons at post-WMAP benchmark points at LHC (CMS)

    We study the possibility of detecting sleptons at post-WMAP benchmark points at LHC (CMS). We find that, at L tot = 30 fb−1, it would be possible to detect sleptons at points B, C, D, G. We also investigate the p...

    LHC (CMS) discovery potential for models with effective supersymmetry and nonuniversal gaugino masses

    We investigate squark and gluino pair production at LHC (CMS) with subsequent decays into quarks, leptons, and the lightest supersymmetric particles (LSP) in models with effective supersymmetry, where the thir...

    Running coupling at low momenta, renormalization schemes, and renormalons

    We propose a method for summing a perturbation-theory asymptotic series that is related to infrared (IR) renormalons in QCD using special renormalization schemes in which the running coupling constant can be i...

    Phenomenology of SU(3)⊗SU(2)⊗U(1) supersymmetric model with Dirac neutrino masses

    We consider a minimal supersymmetric extension of the standard electroweak model with Dirac neutrino masses. In such a model for a significant region of the parameters the right-handed tau sneutrino is the lig...

    Search for flavor lepton number violation in slepton decays at LHC

    SUSY model with R-parity violation and long-lived charged slepton

    We construct a SUSY electroweak model with superweak R-parity violation. The scale of R-parity violation in our model is determined by the Majorana mass of the neutrino and is very small, leading to the existence...
