Flavour and Collider Interplay for SUSY at LHC7

TL;DR

This paper investigates how collider data and flavour physics constraints jointly inform the parameter space of SUSY models, especially in light of potential early signals at the LHC7 run.

Contribution

It analyzes the interplay between collider searches and flavour constraints in three SUSY models, introducing benchmark scenarios to test model consistency.

Findings

Flavour constraints can significantly restrict SUSY parameter space.

Collider and flavour data together improve model parameter determination.

Benchmark scenarios help in testing model viability against experimental results.

Abstract

The current 7 TeV run of the LHC experiment shall be able to probe gluino and squark masses up to values larger than 1 TeV. Assuming that hints for SUSY are found in the jets plus missing energy channel by the end of a 5 fb$^{-1}$ run, we explore the flavour constraints on three models with a CMSSM-like spectrum: the CMSSM itself, a Seesaw extension of the CMSSM, and Flavoured CMSSM. In particular, we focus on decays that might have been measured by the time the run is concluded, such as $B_s\to\mu\mu$ and $\mu\to e\gamma$. We also analyse constraints imposed by neutral meson bounds and electric dipole moments. The interplay between collider and flavour experiments is explored through the use of three benchmark scenarios, finding the flavour feedback useful in order to determine the model parameters and to test the consistency of the different models.
