An analysis of the production of a Higgs boson (H) in association with a top quark-antiquark pair (t (t) over barH) or a single top quark (tH) is presented. The Higgs boson decay into a bottom quark-antiquark pair (H -> b (b) over bar) is targeted, and thr ...
The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of 1.4 x 10(17) protons on dump collected in 2021. No evidence for a dark photon signal is observed. The comb ...
We show that the minimal Weyl-invariant Einstein-Cartan gravity in combination with the Standard Model of particle physics contains just one extra scalar degree of freedom (in addition to the graviton and the Standard Model fields) with the properties of a ...
A search for new physics in top quark production with additional final-state leptons is performed using data collected by the CMS experiment in proton-proton collisions at root s = 13TeV at the LHC during 2016-2018. The data set corresponds to an integrate ...
Measurements of the cross section for the production of top quark pairs in association with a pair of jets from bottom quarks and in association with a pair of jets from quarks of any flavor or gluons and their ratio are presented. The data were collected ...
