The limits from Higgs searches at LEP and the Tevatron play an important role in constraining extensions to the Standard Model, and will need to be taken into account in the interpretation of any new physics observed at the LHC. HiggsBounds is a Fortran code which facilitates this task. It uses the expected and observed topological cross section limits from the charged and neutral Higgs...

In this talk, I report on the comparison of different mass determination methods for BSM scenarios with heavy initial cascade particles and long subsequent decay chains. For any BSM theory, the underlying particle mass spectrum will be among the first available information on the new physics involved. A multitude of techniques is currently available to determine the masses of new particles in...

The LHC could provide many observables from which the parameters of the MSSM can be determined. Technical difficulties in accommodating experimental cuts as well as large theoretical uncertainties have led to absolute rates of SUSY signal events being ignored in favor of more easily-measured observables such as kinematic edges. In this talk, I present a code which calculates a fast...

If supersymmetry is observed at the LHC, the parameters of the MSSM will be measured at the electroweak scale. Using SPS1a as an example, the expected precision on the parameter determination, including a proper treatment of experimental and theoretical errors, is discussed. Particular attention is paid to the question of degenerate solutions at the LHC. Using the SFitter framework a full...

The identification of the correct model for physics beyond the Standard Model
requires the determination of the spin of new particles.
We investigate to which extent the spin of a new particle $X$ can be identified in scenarios where this
particle decays dominantly via three-body decays $X\rightarrow f\overline{f} Y$
where we assume that all intermediate particles are heavy and the...

If supersymmetry is discovered at the LHC, the first task will be to determine the mass spectrum, and to this end Susy Cascade decays would prove extremely useful. However, in order to prove that the model really is supersymmetry, one must measure not only the masses of the new states, but their spins as well. In this talk I will discuss the determination of these superpartner spins using...
