Top, Higgs, and New Physics

In this talk, I will discuss three New Physics scenarios of relevance for current LHC analyses. Firstly, baryon number violation would immediately signal non-standard physics. Enforcing low-energy constraints through minimal flavor violation, such interactions could show up in peculiar top production channels. Further, these interactions may now be much welcome in a supersymmetric context, since they allow to bypass the already tight constraints on sparticle masses. Secondly, the presence of a fourth generation will be reappraised by pointing out the consequences of a mismatch between the number of QCD colors and flavors. Finally, the impact a new light weakly interacting dark particle could have on the Higgs boson searches, and the consequences of the recent hints of a light Higgs boson for such scenarios, will be detailed.
