Top Quark Physics at Hadron Colliders

The top quark, discovered at the Tevatron in 1995 and not long ago re-discovered at the LHC, is strongly coupled to the Higgs sector and therefore expected to be related to electroweak symmetry breaking. From the naturalness problem of the Higgs boson we can expect the existence of a relatively light top partner. Recently, several anomalies have been reported by the experiments at the Tevatron pointing to new physics directly linked with the top quark. Thus, top tagging using jet substructure is an active research area in nowadays. I will talk about the basics of jet substructure analysis, our top tagging approach and several applications for top physics, especially stop searches and the potential of the ttbar forward-backward asymmetry measurement at the LHC.

Recent Electroweak and other Measurements by CMS

I will give an overview of the precision electroweak measurements at the LHC and their usefulness in constraining the parton distribution function and the search for physics beyond the Standard Model. I will focus on the measurements of the rates and asymmetries of inclusive and differential production of W and Z vector bosons in pp collisions at 7 TeV c.m. energy at the CMS detector. I will also cover last minute breaking news from CMS.
