Bottom-Up Reconstruction Scenarios for (un)constrained MSSM Parameters at the LHC

Understand

We consider some specific inverse problem or "bottom-up" reconstruction strategies at the LHC for both general and constrained MSSM parameters, starting from a plausibly limited set of sparticle identification and mass measurements, using mainly gluino/squark cascade decays, plus eventually the lightest Higgs boson mass.

• For the three naturally separated sectors of: gaugino/Higgsino, squark/slepton, and Higgs parameters, we examine different step-by-step algorithms based on rather simple, entirely analytical, inverted relations between masses and basic MSSM parameters.
• This includes also reasonably good approximations of some of the relevant radiative correction calculations.
• We distinguish the constraints obtained for a general MSSM from those obtained with universality assumptions in the three different sectors.
