"New measurements of W±Z production cross-sections in pp collisions at a center-of-mass energy of 13 TeV are presented. The full Run 2 dataset recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1, is used. The W±Z candidate events are reconstructed using leptonic decay modes of the gauge bosons into electrons and muons.

Strict gauge invariance dictates that physical states must be composite, even for the weak sector of the Standard Model. This field-theoretical subtlety is resolved by the Fröhlich-Morchio-Strocchi (FMS) mechanism, which suggests additional Higgs contributions in Standard Model processes. While this has been supported by theoretical investigations in the purely bosonic sector, its implications...

We present the most recent measurements of top production cross sections in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The dataset used was recorded by the CMS experiment at the LHC in special runs recorded in 2017, featuring a low-pileup environment, which offers a clean setting for precise cross-section measurements. Results are compared with state-of-the-art...
