    Search for new physics at LHC

    Full text link
    We review the search for new physics to be performed at the Large Hadron Collider(LHC). Namely, we review the expectations for the Higgs boson, supersymmetry and exotica detection at LHC. We also describe the main parameters of the CMS and ATLAS detectors.Comment: 93 pages, 31 figures, added reference

    Prospects of detecting massive isosinglet neutrino at LHC in the CMS detector

    A possibility to search for a heavy isosinglet (sterile) neutrino using its decay mode νs→l±+2jets\nu_s \to l^{\pm} + 2 jets in the SS - channel production pp→W∗+X→l±νs+Xpp \to W^* + X \to l^{\pm}\nu_s + X in the CMS experiment is studied. The only assumption about the heavy neutrino is its nonzero mixing with νe\nu_e or νμ\nu_{\mu}. The corresponding CMS discovery potential expressed in terms of the heavy neutrino mass and the mixing parameter between the heavy and light neutrino is determined. It is shown that the heavy neutrino with a mass up to 800 GeVGeV could be detected in CMS. We also investigate the production of the heavy neutrino NlN_l mixed with νe\nu_e and/or νμ\nu_{\mu} in the SUC(3)⊗SUL(2)⊗SUR(2)⊗U(1)SU_C(3) \otimes SU_L(2) \otimes SU_R(2)\otimes U(1) model through the reaction pp→WR+X→l±Nl+Xpp \to W_R + X \to l^{\pm}N_l + X with the same heavy neutrino decay channel as above. We find that for MWR<3TeVM_{W_R} < 3 TeV it is possible to discover the heavy neutrino with a mass up to 0.75⋅MWR0.75 \cdot M_{W_R}.Comment: 14 pages, 13 figure

    Relativistic model of hidden bottom tetraquarks

    Full text link
    The relativistic model of the ground state and excited heavy tetraquarks with hidden bottom is formulated within the diquark-antidiquark picture. The diquark structure is taken into account by calculating the diquark-gluon vertex in terms of the diquark wave functions. Predictions for the masses of bottom counterparts to the charm tetraquark candidates are given.Comment: 6 page
