  1. 280. Results of searches for Leptoquarks, Isolated Leptons and Multileptons at HERA

    Results of searches for Leptoquarks, Isolated Leptons and Multileptons with the H1 and ZEUS experiments in ep collisions at HERA are presented. The analyses use the full statistics of HERA high energy running which ended in March 2007. Combined results of both experiments based on a total integrated luminosity of about 1 fb-1 are also shown.

  2. 397. Search for scalar top admixture in the $t\bar{t}\rightarrow\ell+$jets channel with the D0 detector

    We report on a search for scalar top quark pair production in the lepton+jets channel. Just like Standard Model top quarks, scalar top quarks are produced in pairs in proton-antiproton collisions. One of the preferred scenarios is for the scalar top to decay to a b-quark and a chargino, with the chargino subsequently decaying into a real or virtual W boson and a neutralino. The...

  3. 161. Search for the Associated Production of Charginos and Neutralinos with the D0 detector

    A search for associated production of charginos and neutralinos is performed using data recorded with the D0 detector at a p-pbar center-of-mass energy of 1.96 TeV at the Fermilab Tevatron Collider. This analysis considers final states with missing transverse energy and three leptons, including hadronic decays of tau leptons. With more than 2fb-1 of data recorded by the D0 experiment,...

    Parallel Talk
    We present the results of a search for associated production of the lightest chargino and next-to-lightest neutralino using 1fb-1 of sqrt s = 1.96 TeV ppbar data collected with the CDF detector at the Tevatron. We combine the results of several multi-lepton final states to set upper limits on the cross section times branching ratio for chargino-neutralino production as a function...

  5. 325. SUSY searches in trilepton final states at the LHC

    Colliders - Susy Phenomenology
    Parallel Talk
    he direct production of neutralino-chargino pairs in the mSUGRA scenario with decays to a pure trilepton final state has a significant cross section at low neutralino masses and is a viable SUSY discovery channel at the LHC. The main Standard Model background are from Z/gamma + jets, WZ/gamma and ttbar channels where dileptons appear from Z decays and a third lepton is coming either from...
