Ayan Paul (I)28/05/2014, 14:30Higgs PhysicsParallel Session talkPossible extensions of the Standard Model predict modifications of the Higgs couplings to gluons and to the SM top quark. The values of these two couplings can, in general, be independent. We discuss a way to measure these interactions by studying the Higgs production at high $p_T$ within an effective field theory formalism. We also propose an observable $r_\pm$ with reduced theoretical...Go to contribution page

Cedric Delaunay (Unite Reseaux du CNRS (FR))28/05/2014, 14:50Higgs PhysicsParallel Session talkCurrent Higgs data permit a significantly enhanced Higgs coupling to charm pairs, comparable to the Higgs to bottom pairs coupling in the Standard Model, without resorting to additional new physics sources in Higgs production. An immediate consequence of such a large charm coupling is a significant reduction of the Higgs signal strengths into the known final states as in particular into bottom...Go to contribution page

Matthias Josef Schlaffer (Deutsches Elektronen-Synchrotron (DE))28/05/2014, 15:10Higgs PhysicsParallel Session talkThe Higgs production and decay rates offer a new way to probe new physics beyond the Standard Model. While dynamics aiming at alleviating the hierarchy problem generically predict deviations in the Higgs rates, the current experimental analyses cannot resolve the long- and short-distance contributions to the gluon fusion process and thus cannot access directly the coupling between the Higgs...Go to contribution page

Prof. Chung Kao (University of Oklahoma)28/05/2014, 15:30Higgs PhysicsParallel Session talkThe results from the LHC indicate that the couplings of the Higgs boson to other particles are consistent with the Standard Model. However the final and ultimate test as to whether this particle is the standard Higgs boson will be the coupling of the Higgs boson to itself. We study the Higgs pair production from gluon fusion at the LHC and try to determine how accurately the trilinear Higgs...Go to contribution page

Prof. C.S. Lim (Tokyo Woman's Christian University)28/05/2014, 15:50SuSy and other BSM phenomenologyParallel Session talkWe discuss the phenomenological implications of gauge-Higgs unification scenario on the Higgs physics. In the scenario, Higgs is a gauge field in higher dimensional space-time to start with. Thus, the Higgs potential is basically handled by the gauge principle and Higgs mass is related to the weak scale, as in MSSM. As a concrete example, we take 6-dimensional gauge-Higgs unification model,...Go to contribution page

Dr Luca Di Luzio (KIT)28/05/2014, 16:40Higgs PhysicsParallel Session talkAfter reviewing the calculation of the Standard Model one-loop effective potential in a class of linear gauges, we discuss the physical observables entering the vacuum stability analysis. In particular, the field value at which the effective potential turns negative (the so-called instability scale, often associated with the physical threshold of the "new physics") is a gauge dependent...Go to contribution page

Kher Sham Lim (Max-Planck-Institut fuer Kernphysik)28/05/2014, 17:20SuSy and other BSM phenomenologyParallel Session talkThe LHC and other experiments show so far no sign of new physics and long-held believes about naturalness should be critically reexamined. I will discuss models with a combined breaking of conformal and electroweak symmetry by a strongly coupled sector, which serves as a new paradigm in solving the hierarchy problem. For the first model, a strongly coupled hidden sector undergoes spontaneous...Go to contribution page

Archil Kobakhidze (The University of Sydney)28/05/2014, 17:40SuSy and other BSM phenomenologyParallel Session talkWe discuss the relevance of classical scale invariance for a technically natural solution to the problem of the radiative stability of the electroweak scale. Some realistic electroweak scale-invariant models are considered and their possible manifestations at the LHC are briefly discussed.Go to contribution page
