Since the discovery of the Higgs boson in 2012, Higgs physics has entered the precision era, with a key focus on measuring the Yukawa interactions between the Higgs boson and Standard Model fermions. The LHC serves as a crucial Higgs factory, and the High Luminosity LHC (HL-LHC) is expected to provide even more precise measurements due to its increased luminosity. However, effective charm and...
Detailed measurements of Higgs boson properties can be performed using its decays into fermions, providing in particular a key window into the nature of the Yukawa interactions. This talk presents the latest measurements by the ATLAS experiment of Higgs boson properties in its delays into pairs of leptons, using the full Run 2 pp collision dataset collected at 13 TeV.
We present progress on the calculation of the virtual NNLO corrections to $t\bar{t}H$ production in the $q\bar{q}$-channel. We focus on the numerical evaluation of the amplitude, and the associated challenge of constructing a grid to interpolate the amplitude over a 5-dimensional phase space.
The study of Higgs boson production in association with one or two top quarks provides a key window into the properties of the two heaviest fundamental particles in the Standard Model, and in particular into their couplings. This talk presents property measurement of Higgs boson, in particular cross section and CP nature, with tH and ttH production in pp collisions collected at 13 TeV with the...
