Tony Gherghetta (University of Minnesota)3/16/16, 11:10 AMTheoryOrdinaryLong-lived, colour-triplet scalars are a prediction of unnatural, or split, composite Higgs models where the spontaneous global-symmetry breaking scale f≳10 TeV and an unbroken SU(5) symmetry is preserved. Since the triplet scalars are pseudo Nambu-Goldstone bosons, they are split from the much heavier composite-sector resonances and are the lightest exotic, coloured states. Due to discrete...Go to contribution page

Dr Allison McCarn (University of Michigan)3/16/16, 11:30 AMExperimentOrdinaryThe search for extended scalars is an important aspect of the search for physics beyond the Standard Model. New scalar particles are predicted in models with extended Higgs sectors, such as Two-Higgs-Doublet Models, among others. This presentation will feature the latest results for ATLAS and CMS in the search for new scalar particles, including searches with a variety of production...Go to contribution page

Dr Revital Kopeliansky (Indiana University)3/16/16, 5:00 PMExperimentOrdinaryA review of the nonconventional final-states searches performed by both ATLAS and CMS experiments is presented. Detailed results based on data collected during pp collisions at sqrt(S) = 13 TeV are shown, as well as a brief summary of the currently under-construction searches with sqrt(S) = 8 TeV data runs conclusions.Go to contribution page

Dr Martin Jung (TUM Excellence Cluster Universe)3/16/16, 5:20 PMTheoryOrdinaryWe define a new class of Z′ models with neutral flavour-changing interactions at tree level in the down-quark sector. They are related in an exact way to elements of the quark mixing matrix due to an underlying flavoured U(1)′ gauge symmetry, rendering these models particularly predictive. The same symmetry implies lepton-flavor non-universal couplings, fully determined by the gauge structure...Go to contribution page

Clemens Lange (University of Zurich)3/16/16, 5:40 PMExperimentOrdinaryThe increase of the centre-of-mass energy of the Large Hadron Collider (LHC) to 13 TeV has opened up a new energy regime. Final states including high-momentum multi-jet signatures often dominate beyond standard model phenomena, in particular as decay products of new heavy particles. While the potential di-photon resonance currently receives a lot of attention, multi-jet final states pose...Go to contribution page

Dr Felix Bruemmer (LUPM Montpellier)3/16/16, 6:00 PMTheoryOrdinaryIn this talk I consider two-H doublet models (THDMs) with a supersymmetric UV completion. Contrary to the Standard Model, THDMs can be embedded in high-scale supersymmetry with a SUSY breaking scale as high as the scale of grand unification. The stability of the electroweak vacuum and experimental constraints point towards low values of tan(beta) < 2 and a pseudoscalar mass of at least about a...Go to contribution page

Dr Thomas Rizzo (SLAC)3/16/16, 7:25 PMTheoryOrdinaryWe demonstrate that the 3σ excess observed by ATLAS in the Z+MET channel at 8 TeV can be explained within the context of the MSSM. Using the freedom inherent in the pMSSM, we perform a detailed analysis of the parameter space and find a scenario that describes the excess while simultaneously complying with all other search constraints from the Run I data at 7 and 8 TeV, including the...Go to contribution page

Dr Aurora Meroni (CP3-Origins, SDU)3/17/16, 8:55 AMTheoryOrdinaryWe show, via a careful analytical and numerical analysis, that a pseudo Goldstone nature of the Higgs is naturally embodied by an elementary realization that also serves as ultraviolet completion. Renormalizability married to perturbation theory allows to precisely determine the quantum corrections of the theory while permitting to explore the underlying parameter space. By characterising the...Go to contribution page

Elizabeth Jenkins (UCSD and CERN)3/17/16, 9:15 AMTheoryOrdinaryA geometric formulation of Higgs Effective Field Theory (HEFT) is presented.

Henning Kirschenmann (CERN)3/17/16, 9:35 AMRecent results from searches for supersymmetry in final states with one or more leptons by the ATLAS and CMS collaborations are reported. The data for these results have been recorded in 2015 at √s = 13 TeV and amount to an integrated luminosity of 2.2 − 2.3 fb−1 for the CMS experiment and 3.2 fb−1 for the ATLAS experiment. The results are interpreted in simplified models.Go to contribution page

Dr Massimiliano Bellomo (University of Massachusetts Amherst)3/17/16, 10:20 AMExperimentOrdinaryResonant production of two electroweak gauge bosons (WW, WZ, ZZ) is an important signature for physics beyond the Standard Model and various possibilities resulting in such signatures have been proposed, e.g, Extended Gauge Models with heavy charged/neutral bosons (W’, Z’), bulk Randall-Sundrum excitation of the graviton (G*) in extra dimensions. Similarly the resonant production of a W...Go to contribution page

Prof. Aldo Deandrea (IPNL)3/17/16, 10:45 AMTheoryOrdinaryThe diboson resonant excesses reported by both ATLAS and CMS Collaborations in Run 1, can be interpreted a new weak singlet pseudoscalar particle η_WZ which may decay into two weak bosons while being produced in gluon fusion at the LHC. The couplings to the gauge bosons can arise from a Wess-Zumino-Witten anomaly term and thus we study an effective model based on the anomaly term as a well...Go to contribution page

Maurizio Pierini (CERN)3/17/16, 11:25 AMExperimentOrdinaryIn this talk, a few examples of anomalies in the ATLAS & CMS Run I searches will be discussed, in connection with the corresponding preliminary results at 13 TeV. The agreement between the two experiments will be assessed, and the compatibility with the new results will be discussed. The talk will serve as an opportunity to stimulate a discussion on where the search for new physics at the LHC...Go to contribution page
