Resumen de Hunting for new physics signals in the lhc era
Currently, the Standard Model of particle physics is able to satisfactorily explain three out to the four fundamental interactions of matter: strong, weak and electromagnetic interactions. However, there are many aspects that this fantastic theory is not able to explain and there must certainly be something beyond it. This thesis aims to find out if there is any indication in the current data of the accelerators that suggests the existence of new physics. We intend, therefore, to determine to which extent some of the new physics models that have been proposed in the literature may be plausible given current data. In this way, constraints on the parameter space of models that extend the scalar sector of the Standard Model with coloured scalars will be found. In addition, bounds on the new physics electroweak couplings of the top quark will be presented.
