Study of the compressed region of pair production of top squarks in the full-hadronic final states
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...

La supersimetría (SUSY) es una de las teorías propuestas para resolver este problema de manera natural. En particular, en el modelo estándar mínimo supersimétrico (MSSM) con conservación de la paridad R, se requiere que los squarks top (stops) tengan una masa inferior a 1 TeV. Las búsquedas de la producción de pares de stops en el LHC han extendido la región de exclusión para un amplio espectro de masas, sin embargo, hay todavía regiones pequeñas en el espacio de parámetros, llamadas regiones comprimidas, donde las búsquedas no han sido lo suficientemente sensibles.

| description |
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... |
