The large datasets accumulated by the ATLAS and CMS experiments at the CERN LHC allowed to derive very precide measurements of properties of the W and Z bosons and a variety of other electroweak processes. The talk will review the most recent results provided by the two collaborations.
In the Standard Model the three charged leptons are identical copies of each other, apart from mass differences and the electroweak coupling of the gauge bosons to leptons is independent of the lepton flavour. This prediction is called lepton flavour universality (LFU) and is well tested in tree level decays, any violation of LFU would be a clear sign of physics beyond the Standard...
Data from pp collisions at a center-of-mass energy of 13 TeV, corresponding to
an integrated luminosity of 36.1 fb$^{-1}$ has been collected with the ATLAS
detector in 2015 and 2016. In this search, we look at the Standard Model Higgs
boson production in the diphoton channel produced in association with missing
transverse energy using three benchmark models. The analysis is performed in...
The gauge structure of the electroweak sector can be tested by studying diboson final states in proton proton collisions, involving triple and quadratic gauge couplings. In this talk, we will first review the latest precision measurements of diboson final states at a center of mass energy of 13 TeV as well as their interpretation in the view of effective field theories. Moreover, we will...
