Following recent ATLAS and CMS publications we interpret the results of their Higgs searches in terms standard model operators. For a boson mass 125 GeV determine several couplings from published 2011 data extrapolate towards different scenarios LHC running. Even though our analysis is limited by low statistics already derive meaningful constraints on modified sectors.
Higgs couplings can be measured at a linear collider with high precision. We estimate the uncertainties of such measurements, including theoretical errors. Based on these results we show an extrapolation for combined analysis and high-luminosity LHC.
Recent measurements by Planck, LHC experiments, and Xenon100 have significant impact on supersymmetric models their parameters. We first illustrate the constraints in mSUGRA plane then perform a detailed analysis of general minimal Standard Model (MSSM) with 13 free Using SFitter, Bayesian profile likelihood approaches are applied results compared. The allowed structures parameter spaces largely defined different mechanisms dark matter annihilation combination light Higgs mass prediction. In...
SFITTER is a new analysis tool to determine supersymmetric model parameters from collider measurements. Using the set of mass measurements at LC and LHC we show how both colliders probe different sectors MSSM Lagrangian. This observation strong motivation move parameter fit assuming certain unconstrained weak-scale We argue technical challenges can be dealt with in combined fit/grid approach full correlations.

The Galactic Center excess of gamma ray photons can be naturally explained by light Majorana fermions in combination with a pseudoscalar mediator. next-to-minimal supersymmetric Standard Model (NMSSM) provides exactly these ingredients. We show that for neutralinos significant singlino component the linked to invisible decays Model--like Higgs at LHC. find predictions branching ratios 50%, easily accessible Constraining NMSSM through grand-unified-theory (GUT)-scale boundary conditions only...
The increase of the particle flux at HL-LHC with instantaneous luminosities up to L=7.5 × 10 34 cm −2 s −1 will have a severe impact on ATLAS detector reconstruction and trigger performance. end-cap forward region where liquid Argon calorimeter has coarser granularity inner tracker poorer momentum resolution be particularly affected. A High Granularity Timing Detector installed in front calorimeters help charged-particle luminosity measurement. This low angle is introduced augment new...
This collection of studies on new physics at the LHC constitutes report supersymmetry working group Workshop `Physics TeV Colliders', Les Houches, France, 2007. They cover wide spectrum phenomenology in era, from alternative models and signatures to extraction relevant observables, study MSSM parameter space finally interplay observations with additional data expected a similar time scale. The special feature this is that while not each explicitely performed together by theoretical...
