We adopt in this thesis a new approach by assuming a set of $H$-charges that give rise to a self-consistent model of $R$-parity breaking and baryon-number violation. As a consequence of our $H$-charge assignments, it is not possible to…

Supersymmetry with heavy scalars is a model where at the LHC we have to rely on rate measurements to determine the parameters of the underlying new physics. For this example we show how to properly combine rate measurements with kinematic…
