Devdatta Majumder (University of Kansas (KU))05/05/2015, 16:30BSMparallel talkWe present recent results from the CMS experiment of searches for massive vector-like top and bottom quark partners using data collected in proton-proton collisions at centre-of-mass energy of sqrt(s)=8 TeV. These partners can be found in models addressing the hierarchy problem to stabilize the mass of the Higgs boson. The searches span a range of final states, from multi-lepton to entirely...Go to contribution page

Ruchika Nayyar (University of Arizona (US))05/05/2015, 16:45parallel talkThe naturalness argument for theories beyond the Standard Model supports the presence of fermionic top/bottom quark partners, usually referred to as vector-like quarks (VLQs), to cancel mass divergence for the Higgs boson. Searches for vector-like quarks have been performed in various final states with leptons, jets and missing transverse momentum at the ATLAS experiment. This talk...Go to contribution page

Jack Collins (urn:Google)05/05/2015, 17:00parallel talkThe phenomenology of typical charge 2/3 top partners is determined by their decays T -> th, T -> tZ, T -> bW. Recent CMS and ATLAS searches have bounded the mass of such a top partner to be greater than ~700 GeV. We consider a Little Higgs model in which the quadratically divergent top loops are cancelled by a single top partner which is odd under a parity that forbids the couplings...Go to contribution page

Prof. Satyanarayan Nandi (Oklahoma State University)05/05/2015, 17:15parallel talkNon-minimal universal extra dimensions (nmUED) involve the choice of boundary localized kinetic terms (BLKT) for the 5 dimensional gauge bosons and fermions. We find that with suitable choice of these parameters needed to explain the current Higgs data, the BLK terms removes the approximate degeneracy of the KK mass spectrum, and the pair productions of the level-1 quarks and gluons give rise...Go to contribution page

Doojin Kim (University of Maryland)05/05/2015, 17:30parallel talkI will discuss discovery potential of new physics at hadron colliders using the recently proposed on-shell constrained $M_2$ variables. Particular focus is upon new physics signatures in the top quark sector, for which regular pair-produced top quarks are dominant background. The relevant signal processes are featured by an *asymmetric* event topology, whereas top quark pairs are *symmetric*....Go to contribution page

Mr Campoverde Angel (Stony Brook University)05/05/2015, 17:45parallel talkMany extensions to the Standard Model predicts new particles decaying into two massive bosons (WW, WZ, ZZ and HH). Searches for such diboson resonances have been performed in final states with different numbers of leptons and jets including fat-jets with jet substructure. Searches for new physics in other final states are also carried out. This talk summarizes ATLAS searches for...Go to contribution page

Jennifer Ngadiuba (Universitaet Zuerich (CH))05/05/2015, 18:00parallel talkNew results on searches for heavy resonances decaying to pairs of Standard Model bosons (WW, WZ, ZZ, WH, ZH, HH) based on the full dataset (L = 19.7fb-1) of proton-proton collisions at sqrt(s) = 8 TeV collected by the CMS detector at the LHC are presented. Several New Physics scenarios including extra dimensions, composite Higgs models, and the recently proposed heavy vector triplet (HVT)...Go to contribution page

Souvik Das (University of Florida (US))05/05/2015, 18:15Higgsparallel talkSearches for resonant pair production of Higgs bosons at the LHC using the CMS apparatus through various decay channels are presented. The analyses use Run I pp collision data recorded at sqrt(s) = 8 TeV. Upper limits on the production cross section of massive resonances between 250 GeV and 1.1 TeV are reported, and constraints on theories with extended Higgs sectors and Randall Sundrum...Go to contribution page
