R-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...

The 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...

We 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...

We 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...

The 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...

FlexibleSUSY is a mathematica and C++ package which can be used to
create a fast and precise spectrum generator for a SUSY or BSM model
chosen the by the user. 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...

With new data, and hopes for observation of new physics, well on the way with the LHC Run II it is necessary to have computational tools at hand that will link experimental observables to model parameters through a global fit done within a rigorous statistical framework. We present SusyFit, a Markov Chain Monte Carlo based Bayesian Analysis tool that can perform global fits with electroweak...

The analysis of the data collected by the major LHC experiments during the LHC Run I has put strong constraints on supersymmetric models. We study the parameter space of the constrained Minimal Supersymmetric Standard Model (CMSSM) in a global fit, taking into account the non-observation of supersymmetry at the LHC, Higgs mass and rate measurements, as well as several cosmological and low...

We present the prospects for SUSY searches at the LHC, $e^+e^-$ colliders, based on our pMSSM10 analysis as presented in arXiv:1504.03260. This talk is submitted on behalf of the MasterCode collaboration. It is not clear yet who will actually give the talk.

We shall present results of a multi-dimensional fit of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) to the LHC Run 1 results. The emphasis of our study lies in particular on the MSSM Higgs sector. We take into account various experimental constraints and measurements from Higgs searches at the LHC and LEP experiments, using the tools *HiggsBounds* and *HiggsSignals*....

We 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...

I will discuss the prospect of extending the reach for squarks and gauginos via associated production at a $\sqrt{s} = 100$ TeV proton-proton collider, given 3 ab$^{-1}$ integrated luminosity. 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...

Signal 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...

I will discuss a new method of precision top quark mass measurement using bottom quark energy at the LHC. The relevant technique is based upon the observation that if a certain heavier particle decays into a massless visible particle and another particle, the energy peak in the laboratory-frame energy distribution of the visible particle is the same as its corresponding monochromatic energy...

Most 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...

We present recent result for the decay of (heavy) SUSY Higgs bosons into SUSY particles
(sfermions, charginos, neutralinos), based on a full one-loop calculation. We analyze in
particular the dependence on the complex parameters of the model. We find corrections at
the level of 10-20% or higher.

The 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...

We identify a benchmark point in the CMSSM's heavy stau-coannihilation region, which is favored by experiments, and demonstrate that it could be accessible to the LHC at s√=14 TeV with 300/fb of integrated luminosity via a golden decay measurement. With Monte-Carlo, we simulate sparticle production and subsequent golden decay at the event level and perform pseudo-measurements of sparticle...

Recently we proposed the $J_{E_T}$ algorithm in which jets are defined as
subsets of event maximizing some jet functions. In this talk I will discuss
how to generalize the concept to study more complicated configurations,
focusing on the two-prong objects, and its application in studying W/Z/H
decay.

We present NLO QCD accurate predictions of colored scalar pair production matched to parton showers, within a simplified model that can accommodate the case of stop and sgluon pair production. The computation is performed fully automatically within the MadGraph5_aMC@NLO framework, starting from the Lagrangian renormalization with FeynRules and NLOCT down to event generation. This work paves...
