| Summary: | The standard model of particle physics, despite of its overwhelming success, still has some shortcomings to be solved. One of them is the hierarchy problem, where radiative corrections to the mass of the Higgs particle produce divergent quadratic terms. Supersymmetry is one of the theories proposed to solve this problem naturally. In particular, in the Minimal Supersymmetric Standard Model with R-parity conservation, it is required that the mass of the top squark (stop) should be below 1 TeV. Searches for direct stop pair production in the LHC have extended the exclusion region for a wide range of stop masses, however, there are still small regions in the mass parameter space, called compressed regions, where searches have not been sensitive enough. In this work we replicate and extend the searches for strategies and tools that let us explore the compressed region... |
