Tests of the Standard Model and New Phenomena at the Large Hadron Collider

Our current understanding of all elementary particles and their interactions is described by a theory called the Standard Model of Particle Physics. The Large Hadron Collider is testing its validity at previously unexplored regimes by colliding proton beams at energies of tera-electronvolts. Evidence of new phenomena beyond the Standard Model may appear directly, as the production of new particles, or indirectly, as deviations of rates or kinematic distributions from the Standard Model predictions. I will present a concrete example from each scenario. In the first example, I will discuss how measurements of the Drell-Yan differential distribution can be used to infer the running of the electroweak couplings with energy, and test for indirect signs of new physics. In the second example, I will discuss the possibility that new higgs particles may be produced in top-quark decays, and may contaminate standard Higgs searches in the ttH channel.
