Decay chains

As the production of s-quarks and gluinos is favored if kinematically allowed, these particles would start the decay chain in most cases. In the case in which such superparticles were relatively light, the decay chain would be short, and the subsequent possible decays should be few. Instead, if s-quarks and gluinos were very massive, it … Continue reading Decay chains

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

Implications

Fields, masses and coupling constants appearing in the Lagrangian are perturbatively divergent quantities which become acceptable by renormalization procedures. As a consequence, the new quantities are function of the energy and the functional dependence is governed by the Renormalization Group Equations (RGE). For the gauge coupling constants these equations have the form where is the Callan-Symanzik … Continue reading Implications
