Fundamental tests of the Standard Model at ATLAS and CMS — •Baptiste Ravina — Georg-August-Universität Göttingen
The remarkable performance of the Large Hadron Collider (LHC), and of the ATLAS and CMS experiments during Run 1 and Run 2 of the LHC, has opened the door to new fundamental tests of the Standard Model. Detailed knowledge of the detectors during Run 1 allows for high-precision measurements of the W± and Z bosons, while the large Run 2 dataset has revealed further rare electroweak processes.
This talk will highlight some of the successes of the ATLAS and CMS collaborations over the past year, in targeting fundamental aspects of Standard Model physics. Amongst the topics that will be covered are recent measurements of the mass, width and cross sections of the W± and Z bosons; the observation of the elusive, fully electroweak W±W± production process; extractions of αS using very different techniques; and a characterisation of jet and tau production mechanisms. A novel field of research, that of quantum information with high-energy fundamental particles, will be introduced with the observation of quantum entanglement in pairs of top quarks.
