Mr Philip Diessner (TU Dresden (DE))24/08/2015, 14:30Precision Computations and Monte Carlo Tools, all areasR-Symmetry is an additional symmetry which can be imposed on a supersymmetric model, leading to interesting phenomenological consequences like the prediction of Dirac Gauginos. A model with a minimal implementation of this symmetry is the MRSSM and in this talk an analysis of its Higgs sector in the light of the recent SM-like Higgs boson discovery will be presented. Due to mixing with...Go to contribution page

Anja Butter24/08/2015, 14:50Precision Computations and Monte Carlo Tools, all areasThe NMSSM is, for several reasons, an attractive extension of the Standard Model. One of them is that the gamma ray excess from the galactic center can be explained with an NMSSM neutralino annihilating through a light pseudoscalar. Such light dark matter candidate will lead to invisible Higgs decays at the LHC. Using SFitter we connect the galactic center excess with the observed dark...Go to contribution page

Jorge de Blas (INFN Rome)24/08/2015, 15:10Precision Computations and Monte Carlo Tools, all areasWe present updated global fits of the Standard Model and beyond to electroweak precision data, taking into account recent progress in theoretical calculations and experimental measurements. From the fits, we derive model-independent constraints on new physics by introducing oblique and epsilon parameters, and modified $Zb\bar{b}$ and $HVV$ couplings. Furthermore, we also perform fits of...Go to contribution page

Debtosh Chowdhury (INFN, Roma)24/08/2015, 15:30Precision Computations and Monte Carlo Tools, all areasWe determine the next-to-leading order renormalization group equations for the Two-Higgs-Doublet model with a softly broken $Z_2$ symmetry and CP conservation in the scalar potential. We use them to identify the parameter regions which are stable up to the Planck scale and find that in this case the quartic couplings of the Higgs potential cannot be larger than 1 in magnitude and that the...Go to contribution page

Tim Stefaniak (SCIPP, UCSC)25/08/2015, 16:30Precision Computations and Monte Carlo Tools, all areasThe public computer tool *HiggsSignals* evaluates the chi-squared compatibility of the Higgs sector predictions of new physics models with the mass and rate measurements of the 125 GeV Higgs boson discovered at the LHC. It is designed for the application to extended Higgs sectors and automatically considers potential signal overlap of multiple Higgs bosons. The chi-squared test takes into...Go to contribution page

FlexibleSUSY is distributed with a large number of models already implemented and the user may also add new models of there own by creating simple model files. The spectrum generators created by FlexibleSUSY are very fast and the...Go to contribution page

James Gainer (University of Florida (US))27/08/2015, 16:30Precision Computations and Monte Carlo Tools, all areasWe provide a readily generalizable procedure for determining the number of sparticle mass hierarchies in a given SUSY model. As an application, we analyze the gravity-mediated SUSY breaking scenario with various combinations of GUT-scale boundary conditions involving different levels of universality among the gaugino and scalar masses. For each of the eight considered models, we provide the...Go to contribution page

Depending on the gluino mass, the discovery reach for squarks in associated production with a gluino can be up to 40 TeV for compressed spectra (small gluino-LSP mass splitting), and up to 32 TeV for...Go to contribution page

Paul Douglas Jackson (University of Adelaide)27/08/2015, 17:10Precision Computations and Monte Carlo Tools, all areasSignal events where multiple missing neutral particles are present in a final state represent challenging topologies to search for new physics at the LHC. The key to any search is the ability to separate background-like events from signal-like events. Identifying such signal-like events, and extracting their properties, is exacerbated by a lack of knowledge of the particle masses and some...Go to contribution page

Asher Berlin (University of Chicago)28/08/2015, 14:00Precision Computations and Monte Carlo Tools, all areasMost models of WIMPs that possess sizable tree-level interactions with the electroweak bosons of the Standard Model are under ever increasing pressure from the relentless Moore's law like progression of today's direct detection experiments. This has led many to consider various scenarios in which the dark matter candidate instead possesses 1 and 2-loop induced couplings to quarks and gluons at...Go to contribution page

Gabriel Lee (Technion)28/08/2015, 14:40Precision Computations and Monte Carlo Tools, all areasThe MSSM leads to precise predictions of the properties of the light Higgs boson degrees of freedom that depend on only a few relevant supersymmetry breaking parameters. There is an upper bound on the mass of the lightest neutral Higgs boson, which for a supersymmetric spectrum of the order of a TeV, is barely above the measured M_h = 125 GeV at the LHC. Raising this bound by considering a...Go to contribution page
