    I will present the computation of the two-loop scattering amplitude for the associated hadron production of a top pair and a $W$ boson, in the leading color approximation. This result contributes to the virtual part of the NNLO QCD corrections to this process. The amplitude is expressed in terms of a basis of special functions multiplied by kinematic-dependent rational coefficients. The...

    Francesco Confortini (Istituto Nazionale di Fisica Nucleare)

    The top quark, as the most massive elementary particle, plays a crucial role in probing the electroweak sector and the flavour structure of the Standard Model (SM). Its decay hierarchy, dominated by the t → W b transition with highly sup- pressed t → W d/s channels, is governed by the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Precision measurements of single-top quark production at the LHC offer...
