Session B02: New Results from the CERN LHC

Live

The talk will highlight latest results on top quark physics at the LHC employing pp collision data. With millions of top quarks already collected at the LHC top quark physics enters the precision era and differential cross section measurements and top quark property measurements are challenging the Standard Model predictions. The presentation focuses on the latest measurements at ATLAS and CMS employing data collected at a center-of-mass energy of 13 TeV. An overview of the latest status on measurements of top quark mass, angular correlations, single top quark production, associated production of top quarks, and rare decays of top quarks. In particular, the intimate connection of the top quark to the Higgs Boson is scrutinized by highly precise direct measurements of the top quark mass, with alternative approaches entering the precision realm as well. Deviations in the top quark sector between theory and experimental measurements might indicate first hints for new physics. The talk concludes with implications for the SM and an outlook towards the ultimate precision frontier at the high-luminosity phase of the LHC.

The discovery of standard model (SM)-like Higgs Boson in 2012 using data from LHC Run I was only a first small step to fully understanding the nature of this new and unique particle. Since the discovery, the ATLAS and CMS experiments have collected roughly 7 times more data at the higher center of mass energy of 13 TeV. Results on SM Higgs measurements from ATLAS and CMS will be shown using data collected from the LHC Run II, with focus on the most recent ones. Precision measurements, including the Higgs mass, simplified template cross-section (STXS), differential cross-sections and recent searches for rare Higgs decays will be discussed.

Recent results will be presented on searches for physics beyond the standard model from the ATLAS and CMS experiments at the CERN LHC. With the use of advanced techniques and 2-4 times more data, these results have achieved substantial improvements in their expected sensitivity . Exotic searches will include classic signatures from dijets, dileptons, and dibosons, as well as for the invisible decay of the Higgs boson to dark matter. Supersymmetry searches will include searches for the supersymmetric partners to the top quark, and to the electroweak gauge and Higgs bosons. The interpretation of these results for dark matter will also be presented.
