Abstract: Associated production of the Higgs boson with a top quark-antiquark pair (π‘π‘Μ π») provides the best direct probe of the top-Higgs Yukawa coupling at tree-level. Measurement of this coupling is important not only to confirm the predictions made by the Standard Model but also to search for indications of new physics. In this talk, I will present an analysis of π‘π‘Μ π» production with the Higgs boson decaying to a ππΜ pair which has the largest branching fraction. Latest results obtained using pp collision data at the CERN LHC recorded by the CMS experiment at βπ = 13 TeV between 2016 and 2018 corresponding to an integrated luminosity of 138 ππβ1 will be shown. One particularly challenging background limiting the precision of this measurement arises from direct π‘π‘Μ +ππΜ production. Measurements of both the overall π‘π‘Μ π» production rate and in intervals of Higgs boson transverse momentum are performed. Limits are also set on the production rate of a Higgs boson with a single top quark (π‘π») and on the strength and structure of the top-Higgs coupling from simultaneous measurements of π‘π‘Μ π» and π‘π» production rates. In order to improve the precision of these measurements in the future, the LHC in the High Luminosity era will be upgraded to deliver instantaneous luminosities much higher than the original design value. ME0 is a new muon sub-detector (using Gas Electron Multiplier technology) that will be added in the far-forward region (2.0<|π|<2.8) of CMS as part of the Phase-2 Upgrade. I will discuss the development of the readout electronics for the ME0 detector, which must be designed to deal with high data rates and be sufficiently radiation hard to operate so close to the beamline.
