HEP - ASTRO SEMINAR | Laying the Groundwork for Precision Map of the Higgs Sector: Measurement of the ttbarW and ttbarZ Cross-Sections
Detailed exploration of the Higgs sector is central to the long-term physics program of the LHC experiments. Specifically, the precision direct measurement of the coupling between the top quark and the Higgs boson is a key component of the program. To prepare for the future measurements, we study similar processes with higher cross-sections: final states with a massive vector boson and a pair of top quarks, ttbarW and ttbarZ, produced in proton-proton collisions. I will discuss the latest measurements of the ttbarW and ttbarZ cross sections by the ATLAS experiment at the LHC and future prospects for their impact on the precision measurements of the top-to-Higgs coupling.
