I will present the impact of the recent measurements of Planck, LHC experiments and Xenon100 in terms of constraints on supersymmetric parameters. I will consider two models: mSUGRA for an illustration, and a more general Minimal Supersymmetric Standard Model with 13 free parameters. The analysis is done with the SFitter tool allowing a comparison of Bayesian and profile likelihoods results. I will pin point how the allowed structures in the parameter spaces are driven by the combination of the dark matter annihilation mechanisms and the light Higgs mass predictions.

### Where is SUSY?

"... The direct searches for Superymmetry at colliders can be complemented by direct searches for dark matter (DM) in underground experiments, if one assumes the Lightest Supersymmetric Particle (LSP) provides the dark matter of the universe.

The direct searches for Superymmetry at colliders can be complemented by direct searches for dark matter (DM) in underground experiments, if one assumes the Lightest Supersymmetric Particle (LSP) provides the dark matter of the universe. It will be shown that within the Con-strained minimal Supersymmetric Model (CMSSM) the direct searches for DM are complementary to direct LHC searches for SUSY and Higgs particles using analytical formulae. A combined excluded region from LHC, WMAP and XENON100 will be provided, showing that within the CMSSM gluinos below 1 TeV and LSP masses below 160 GeV are ex-cluded (m1/2> 400GeV) independent of the squark masses. 1

For the preparation of the experimental search for charged Higgs bosons at the LHC detailed stud-ies have been made to determine the expected charged Higgs boson production cross-sections and decay branching ratios at s = 14 TeV. In the mass regime below the t-quark mass the expected production cross-sections are discussed using PYTHIA and FeynHiggs program packages based on the decay t → H+b. For higher masses Next-to-Leading-Order (NLO) calculations have been used, and particular attention has been given to the intermediate-mass region. The decay branch-ing ratios have been studied with the program packages FeynHiggs and HDecay. Higher-order corrections (∆b corrections) in the MSSM are consistently taken into account. Two benchmark scenarios are considered, one of them the ‘mhmax’.

### LAPTH-1079/04 CERN-PH-TH/2004-253 Comparison of SUSY spectrum calculations and impact on the relic density constraints from WMAP

, 2005

"... We compare results of four public supersymmetric (SUSY) spectrum codes, ISAJET7.71,SOFTSUSY1.9,SPHENO2.2.2 andSUSPECT2.3 to estimate the presentday uncertainty in the calculation of the relic density of dark matter in mSUGRA models. We find that even for mass differences of about 1 % the spread in t ..."

We compare results of four public supersymmetric (SUSY) spectrum codes, ISAJET7.71,SOFTSUSY1.9,SPHENO2.2.2 andSUSPECT2.3 to estimate the presentday uncertainty in the calculation of the relic density of dark matter in mSUGRA models. We find that even for mass differences of about 1 % the spread in the obtained relic densities can be 10%. In difficult regions of the parameter space, such as large tan β or large m0, discrepancies in the relic density are much larger. We also find important differences in the stau co-annihilation region. We show the impact of these uncertainties on the bounds from WMAP for several scenarios, concentrating on the regions of parameter space most relevant for collider phenomenology. We also discuss the case of A0 = 0 and the stop co-annihilation region. Moreover, we present a web application for the online comparison of the spectrum codes. 1
