Local Supersymmetry

As already seen, the MSSM contains a high number of degrees of freedom. The impossibility to have guidelines on how build a theory leads to models that consider the Supersymmetry as a local symmetry spontaneously broken at different scales with respect to the weak one. Among these, the gravity mediated Supersymmetry breaking theories (or briefly SUperGRAvity, … Continue reading Local Supersymmetry

Beyond the force that holds us back in bed in the morning, there are other four fundamental forces, in Nature. At the present state of our knowledge, Nature is presented as the result of the composition of the four fundamental interactions (electromagnetic, weak, strong and gravitational) with a set of elementary particles which can be classified according … Continue reading Particles and forces
