Measurements of differential and double-differential cross sections of top-quark pair (tt¯)
production are presented in the lepton+ jets channels with a single electron or muon and …

Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been
ongoing. Besides its mass, its width—related to its lifetime—is an important parameter. One …

Results are presented from a search for new physics in high-mass diphoton events from
proton-proton collisions at $\sqrt {s} $= 13 TeV. The data set was collected in 2016-2018 …
