A possible return on race

Third generation superparticles search is one of the main goals of the present LHC activities. Previous LHC data has been especially effective in ruling out the existence of coloured supersymmetric particles (primarily the gluino and the first two generations of s-quarks) with masses below . However, such constraints are relaxed, in some cases by as much as a factor … Continue reading A possible return on race

Production

Production of supersymmetric particles and their subsequent decay chains could occur in different ways depending on the theoretical scenario considered. In the researches for supersymmetric particles, the most frequent choice is to limit the quest to a specific model in which the particles have well-defined decay modes. One of the most promising models to take … Continue reading Production

Supersymmetry searches

As discussed before, SUSY theories introduce the existence of particles at the TeV scale, so these could be already accessible at the . The search for these particles and the determination of their properties, such as mass, spin, etc. and their coupling becomes of central importance in order to verify the existence of new Physics … Continue reading Supersymmetry searches

The Minimal Supersymmetric extension of the Standard Model (MSSM)

The starting point for the construction of the Lagrangian of a such model is the SUSY Lagrangian, where the gauge invariance with respect to the group of the SM, , has to be imposed. In the minimal hypothesis, each particle included in the SM possesses a unique superpartner, i.e. formally a superfield has to replace … Continue reading The Minimal Supersymmetric extension of the Standard Model (MSSM)
