Bruno Lenzi (CERN)8/5/16, 9:00 AMHiggs PhysicsOral PresentationThe search for a spin-0 or spin-2 state decaying into two photons in a large mass range is presented, using about 10 fb-1 of p-p collisions at 13 TeV.Go to contribution page

Chiara Ilaria Rovelli (Universita e INFN, Roma I (IT))8/5/16, 9:20 AMHiggs PhysicsOral PresentationA search for new physics in high-mass diphoton events is presented. The analysis is performed by looking for bumps on the continuum diphoton mass spectrum. This clean signature is sensitive to high-mass gravitons predicted by models with extra dimensions and to scalar resonances arising from many extensions of the standard model. The talk focuses on the recent results obtained using data...Go to contribution page

Michael Fedderke (University of Chicago)8/5/16, 9:40 AMBeyond the Standard ModelOral PresentationThe recently-proposed relaxion framework aims to provide a novel dynamical solution to the Standard Model hierarchy problem. We examine the phenomenology of a new TeV-scale QCD-like sector associated with particular relaxion models in which non-perturbative effects in the new sector provide the stopping-potential for the relaxion. Among the host of potential new-physics signals, whose impact...Go to contribution page

pyungwon ko (Korea Inst. for Advanced Study (KIAS))8/5/16, 9:55 AMBeyond the Standard ModelOral Presentation
We consider a dark sector with SU(3)C×U(1)Y×U(1)X and three families of dark fermions that are chiral under dark U(1)X gauge symmetry, whereas scalar dark matter X is the SM singlet. U(1)X dark symmetry is spontaneously broken by nonzero VEV of dark Higgs field ⟨Φ⟩, generating the masses of dark fermions and dark photon Z′. The resulting dark Higgs boson ϕ can be produced at the LHC by dark...

Krzysztof Rolbiecki (University of Warsaw)8/5/16, 10:10 AMBeyond the Standard ModelOral PresentationWe propose an NMSSM scenario that can explain the excess in the diphoton spectrum at 750 GeV recently observed by ATLAS and CMS. We show that in a certain limit with a very light pseudoscalar one can reproduce the experimental results without invoking exotic matter. The 750 GeV excess is produced by two resonant heavy Higgs bosons that subsequently decay to light pseudoscalars. Each of these...Go to contribution page

Christophe Royon (University of Kansas (US))8/5/16, 10:25 AMBeyond the Standard ModelOral PresentationA slight excess has been observed in the first data of photon-photon events at the 13~TeV LHC, that might be interpreted has a hint of physics beyond the Standard Model. We show that a completely model-independent measurement of the photon-photon coupling of a putative 750 GeV resonance will be possible using the forward proton detectors scheduled at ATLAS and CMS. We consider the...Go to contribution page

qaisar shafi (university of delaware)8/5/16, 10:40 AMBeyond the Standard ModelOral PresentationInspired by the 750 GeV resonance displayed in Run II by the ATLAS and CMS experiments, we propose to incorporate it in an extension of the MSSM based on a suitable gauge symmetry G. The combination of G and a U(1) R-symmetry yields a unique renormalizable superpotential containing a G-singlet superfield S, such that G breaks to MSSM at scale M with supersymmetry unbroken. The mass of the...Go to contribution page

Jack Gunion (University of California Davis (US))8/5/16, 10:55 AMHiggs PhysicsOral PresentationWe present a possible interpretation of the excess in the di-photon channel at 750 GeV recently observed by ATLAS and CMS as the radion of the five-dimensional Randall-Sundrum model. We show that the Higgs-radion scenario can give a cross section of (5--15) fb in the di-photon final state at 750 GeV while at the same time giving a very SM-like state at 125 GeV. Tests of the model using other...Go to contribution page
