Measurements of the four-lepton invariant mass spectrum are made with the ATLAS detector, using proton-proton collisions at √s=13 TeV delivered by the Large Hadron Collider. The measurement is done selecting events that contain two same-flavour opposite-sign lepton pairs. The four-lepton mass exhibits a rich structure, with different mass regions dominated by single Z production, Higgs...
The cross-section of top-quark-antiquark pair production in association with a photon is important in order to determine the electromagnetic coupling of the top-quark with high precision. It is also of great significance to test deviations from the Standard Model (SM), such as anomalous dipole moments of the top-quark. Furthermore, such cross-section can be interpreted in effective field...
The study of the associated production of W and Z bosons is performed in proton-proton collisions using data collected by the CMS experiment. WZ production is one of the dominant multiboson production processes at the LHC energies. Thus, a good understanding of this process improves our understanding of the Standard Model. Inclusive cross section measurements and differential cross section...
The measurement of the top-quark anomalous electromagnetic couplings is one of the most
important goals of the top-quark physics program in the present and future collider experiments.
This would provide direct information on the non-standard interactions of the top-quark. We study
a top-quark pair production scenario at the Future Circular Hadron-Electron Collider (FCC-he)
through $e^-p...
The Standard Model as a very successful theory of electroweak interactions postulates the basic assumption about the pure „V(ector)-A(xial vector)“ character of the interaction. Nevertheless, even after more than half a century of development of the model and experimental testing of its fundamental ingredients, experimental data still rule out the existence of other types of weak interactions...
Single top quark production is the subleading production process of top quarks at the LHC after the top quark pair production. The latest differential measurements of single top quark production cross sections are presented using data collected by the CMS detector at a center-of-mass energy of 13 TeV. The cross sections are measured as a function of various kinematic observables of the top...
The dominant electroweak production mechanism for single top quarks is the $t$-channel and, it features a tWq vertex, where q stands for b, s, or d quarks, both in production and in decay. For this reason its cross section and branching fractions are sensitive to the strength of the electroweak coupling, making it a suitable channel for direct measurements of the magnitude of...
A measurement of the production cross section for high transverse momentum top quark pairs is reported. The data set was collected during 2016 with the CMS detector at the LHC from pp collisions at 13 TeV, and corresponds to an integrated luminosity of 35.9 fb-1. The measurement uses events where either both top quark candidates decay hadronically and are reconstructed as large-radius jets...
