In process

Relations between electroweak parameters can be measured with ever-increasing precision and a future lepton collider will require major advances in the theoretical predictions. We derive top-quark mediated four-loop QCD corrections to $Δr$ and $Δκ$, that is to the relations between the weak boson masses, the electroweak couplings, and the weak mixing angle. [...]

A measurement is presented of dijet angular distributions in proton-proton collisions at s=13TeV, using data collected with the CMS detector at the CERN LHC and corresponding to an integrated luminosity of 138 fb−1. For the first time, the dijet angular distributions, corrected for detector effects, are compared with the predictions of perturbative quantum chromodynamics at next-to-next-to-leading order, including next-to-leading-order electroweak corrections. [...]

A search for Higgs boson (H) production at high transverse momentum (p$_{T}$) in the WW decay channel is presented. The analysis uses proton-proton collisions at $ \sqrt{s}=13 $ TeV recorded by the CMS experiment in 2016–2018, corresponding to an integrated luminosity of 138 fb$^{−1}$ [...]

The jet mass of W bosons decaying to a quark-antiquark pair is measured in W+jets events from proton-proton collisions at a center-of-mass energy of 13 TeV. The data used were collected by the CMS experiment at the CERN LHC and correspond to an integrated luminosity of 138 fb$^{-1}$. [...]

The single top quark t-channel production cross section is measured in proton-proton collisions at the CERN LHC at $ \sqrt{s}=5.02 $ TeV, using data recorded with the CMS detector in 2017, corresponding to an integrated luminosity of 302 pb$^{−1}$, and resulting in the first CMS measurement of the process at that energy. Events with one electron or muon and two or more jets, among which at least one is identified as originating from a b quark fragmentation, are analyzed [...]
