Theory work hopefully started in 2012.
9 msugra msugra MSSM parameter introduces 105 new parameter Makes probing the parameter space very difficult. To make progress, one assumes that MSSM is a low energy realization of some underlying unified theory which broken at some higher energy. One such assumption is msugra (minimal SUper GRAvity) which in it s simplest form depends on 5 parameters at the GUT scale, m 0,m 1/2,A 0,tanβ,sign[µ] m 0,m 1/2 : Universal sfermino and gaugino masses at GUT A 0: Universal trilinear coupling at GUT tanβ: Ratio between neutral Higgs vev s at GUT sign[µ]: Sign of Higgs mixing parameter. By using Renormalization Group Equations (RGE) we obtain the SUSY masses spectrum at low energies.
10 SUSY with τ s Coannihilation Region The majority of msugra parameter space yields to much DM compared to cosmological constraints
11 SUSY with τ s Coannihilation Region The majority of msugra parameter space yields to much DM compared to cosmological constraints Loophole in the τ- χ coannihilation region, where coannihilations reduce DM relic densities
12 SUSY with τ s Coannihilation Region The majority of msugra parameter space yields to much DM compared to cosmological constraints Loophole in the τ- χ coannihilation region, where coannihilations reduce DM relic densities This mass degeneracy also typically leads to a large branching fractions to τ s
13 SUSY with τ s Coannihilation Region The majority of msugra parameter space yields to much DM compared to cosmological constraints Loophole in the τ- χ coannihilation region, where coannihilations reduce DM relic densities This mass degeneracy also typically leads to a large branching fractions to τ s We search for SUSY by looking at signatures with τ s +jets + /E T arising from SUSY cascade decays Figure: Signal process
14 SUSY with τ s Excluded Grid For tanβ < 40, m 0 < 400, m 1/2 < 300 most parameter points are already exluded by accelerator constraints.
15 SUSY with τ s Excluded Grid For tanβ < 40, m 0 < 400, m 1/2 < 300 most parameter points are already exluded by accelerator constraints. In higher mass region, cross section drops fewer constraints. New data and higher statistics allows us to probe higher.
16 SUSY with τ s Excluded Grid For tanβ < 40, m 0 < 400, m 1/2 < 300 most parameter points are already exluded by accelerator constraints. In higher mass region, cross section drops fewer constraints. New data and higher statistics allows us to probe higher. We extend search to higher tanβ,m 0 & m 1/2 to look for points with viable DM candidates and detectable τ signatures.

28 Results Preliminary Conclusions Moving up in parameter space we find models which seem to avoid experimental constraints and gives reasonable values for the Higgs mass and DM relicdensity.
29 Results Preliminary Conclusions Moving up in parameter space we find models which seem to avoid experimental constraints and gives reasonable values for the Higgs mass and DM relicdensity. Cross sections are rather small but the models might be probable with LHC 2011/2012 data(?).
30 Results Preliminary Conclusions Moving up in parameter space we find models which seem to avoid experimental constraints and gives reasonable values for the Higgs mass and DM relicdensity. Cross sections are rather small but the models might be probable with LHC 2011/2012 data(?). Note that softening the Higgs mass cut to M h0 > 110 opens up large regions of parameter space and yields points with cross sections up to 3pb.

Note that softening the Higgs mass cut to M h0 > 110 opens up large regions of parameter space and yields points with cross sections up to 3pb. Very preliminary results, need more knowledge on the uncertainties in the derived parameters in order to know wether the results are reliable.
