Abstract

The Large Hadron Collider (LHC) is entering now a new era, bringing rare and highly energetic events to experimental reach. Unlike the previous period, when we had a clear idea of what to search for, now we have a considerable number of attractive theories that must be tested in this new Higgs sector, which requires a greater collaboration between experimental and theoretical physicists. The objective of this project is to combine efforts on both sides to analyse the top-anti-top-Higgs (ttH) channel. The student will be an active member of the CMS collaboration, where he will carry out this analysis (on a specific final state), and at the same time he will be guided by theoreticians for the formulation of simplified models that contribute significantly to this channel.
