Description
In this talk, I will present a summary of our calculations for the production of $W^{+} W^{-}$ pairs through leptonic decay channels $W^+W^- \to l^+\nu_l + l^{\prime -} \nu_{l'}$ in the framework of $k_t$-factorization. The calculations are performed using the TMD-PDFs of KMR, in different kinematic setups and the results are compared against their counter-part collinear predictions (from HERWIG7 event generator) as well as the existing experimental data from the ATLAS and the CMS collaborations for 8 and 13 TeV. A similar attempt has been made for the case of $W$-boson pair production through the $gg \to H \to W^+W^-$ channel, which is of considerable phenomenological interest at the NNLO QCD accuracy, for both the SM and BSM. We particularly target this NNLO sub-process, since its BSM sensitivity is of critical importance. It will be shown that our present SM predictions for the $W^+W^-$ boson pair production signal would provide the necessary and reliable SM base-line for the future BSM studies.
