Abstract
A review is presented of searches performed by CMS experiment for new particles produced in association with or decaying to top quarks, as well as heavy top partners. The analysis presented use data collected with CMS experiment during 2012, in proton-proton collisions at a centre-of-mass energy of 8 TeV.
Highlights
After the discovery of a SM-like Higgs boson [1, 2], an explanation for the scale of its mass became of great importance
Many searches have been performed by CMS experiment [3] for new particles produced in association with or decaying to top quarks, as well as heavy top partners [4]
Mass reconstruction methods are developed for leptonic final states including one or two invisible particles [8,9,10]
Summary
After the discovery of a SM-like Higgs boson [1, 2], an explanation for the scale of its mass became of great importance New particles, such as heavy top partners, could improve our understanding of the problem, through cancelations in the radiative corrections of the Higgs boson mass. Many searches have been performed by CMS experiment [3] for new particles produced in association with or decaying to top quarks, as well as heavy top partners [4]. Sophisticated algorithms have been developed for tagging top quarks and estimating the mass of their hadronic decays [5,6,7] These techniques allow the reconstruction of invariant mass observables in many final states, a powerful tool to discrimimate possible new resonances from their background processes.
