Andrea Coccaro (University of Washington (US))07/05/2013, 16:30parallel talkSeveral extensions of the Standard Model predict the existence of massive long-lived particles, some of these postulate the existence of a hidden sector of particles. We report on searches for weakly-interacting long-lived particles decaying to collimated lepton-jets far away from the interaction point, and for production of multi-charged particles. The talk presents the final results of...Go to contribution page

Claude Patrick J Nuttens (Universite Catholique de Louvain (BE))07/05/2013, 16:45parallel talkResults of searches for heavy stable charged particles produced in pp collisions at sqrt(s) = 7 and 8 TeV are presented. Data collected with the CMS detector are used to study the momentum, energy deposition, and time-of-flight of candidate events. Fermions with an electric charge of e/3 to 5e as well as bound states suffering from charge flipping (charged to/from neutral) are studied....Go to contribution page

Bryan Ostdiek (University of Notre Dame)07/05/2013, 17:00parallel talkWe study the implications at the LHC for the minimal (least) version of the su- persymmetric standard model. In this model supersymmetry is broken by gravity and extra gauge interactions effects, providing a spectrum similar in several aspects to that in natural supersymmetric scenarios. Having the first two generations of sparticles partially decoupled means that any significant signal...Go to contribution page

Nikiforos Nikiforou (Columbia University (US))07/05/2013, 17:15parallel talkAn extended QCD sector beyond the minimal supersymmetric standard model or the admission of R-parity violation introduces new signatures to the search for supersymmetry at the LHC. Strongly interacting resonances may decay to jets, sleptons may decay via lepton-flavour violating processes and lightest supersymmetric particles may decay into many leptons with or without missing transverse...Go to contribution page

Aniket Joglekar (The University of Chicago)07/05/2013, 17:30parallel talkThe vector-like leptons provide an anomaly free minimal extension of the standard model. Such a model provides a good handle on the Higgs to diphoton decay rate as well as a good dark matter candidate. Due to the yukawa couplings of the new leptons, the Higgs quartic coupling runs negative at the scale of a few TeVs. The presence of the super-partners of the new leptons below the TeV scale can...Go to contribution page

Michael Saelim (Cornell University)07/05/2013, 17:45parallel talkDespite suggestions from naturalness that stops and gluinos should appear at or below the TeV scale, MET-based LHC searches have not yielded any superpartners so far. Consequently, R-parity violating (RPV) SUSY models have gained renewed interest, especially those imposing the Minimal Flavor Violation (MFV) hypothesis. We consider a simplified model with a light gluino and stop with MFV...Go to contribution page

Chris Brust (Johns Hopkins University)07/05/2013, 18:00parallel talkWhether the Standard Model is natural or not is a question that has piqued the interest of theorists since its advent. R-parity violating natural supersymmetry is a BSM model which can evade new physics search strategies currently being performed by CMS and ATLAS. We propose a new search looking for a sbottom decaying to jets plus a W, designed to increase LHC coverage of the parameter space...Go to contribution page

Alexander Moreno Briceno (SUNY at Buffalo, Universidad Antonio Narino)07/05/2013, 18:15parallel talkWe investigate possible CP violating effects due to one loop corrections to top-quark pair production at the LHC in the context of the complex MSSM with minimal flavor violation (MFV). We include the complete supersymmetric QCD as well as supersymmetric electroweak contributions to the top-quark pair production mechanisms, namely quark-antiquark annihilation, qq → tt, and gluon fusion, gg →...Go to contribution page
