M_CT2 (Constransverse mass) variable has unique properties which can be utilized in the new particle mass measurement of SUSY-like events including multiple missing particles. We present the recent developments on using the M_CT2 for resolving new particle masses.

If collider experiments demonstrate that the Minimal Supersymmetric Standard Model (MSSM) is a good description of nature at the weak scale, the experimental priority will be the precise determination of superpartner masses. These masses are governed by the weak scale values of the soft supersymmetry (SUSY)-breaking parameters, which are in turn highly dependent on the SUSY-breaking scheme...

Supersymmetry and other physics beyond the Standard Model (SM) can modify the relations between electroweak observables and their theoretical predictions. Such effects can be parametrized in terms of effective, so-called oblique parameters. A global fit of the electroweak SM, as performed with the Gfitter package, allows one to determine the oblique parameters and to derive constraints on new...

We propose the "SUSY-Yukawa sum rule", a relationship between physical masses and mixing angles of the third-generation quarks and squarks. The sum rule follows directly from a relation between quark and squark couplings to the Higgs, enforced by SUSY. It is exactly this relation that ensures the cancellation of the one-loop quadratic divergence in the Higgs mass from the top sector. Testing...

Supersymmetry (SUSY), with its multi-parameter space, has been a popular playground for many years. But now that the Large Hadron Collider (LHC) is operational, the goal is to determine whether this playground has anything to do with reality. In principle, the Bayesian approach provides a well-founded, coherent, way to perform such studies. However, such studies face a common problem: the...

We investigate the MSSM with very large tan(beta) > 50, where the fermion masses are strongly affected by loop-induced couplings to the "wrong" Higgs, imposing perturbative Yukawa couplings and constraints from flavour physics. Performing a low-energy scan of the MSSM with flavour-blind soft terms, we find that the branching ratio of B->tau nu and the anomalous magnetic moment of the muon are...

SUSY pair productions at the LHC are studied at the next-to-leading corrections with the MadGraph/MadDipole+GOLEM framework. We present the NLO cross sections and discuss the perturbative behavior.
