The CMS collaboration has published the first direct observation of the coupling between the Higgs boson and the top quark.
The annual conference is an opportunity to review the progress taking place over the breadth of particle physics.
The Higgs-boson decay to two W bosons (H → WW) is the second most common decay mode after its decay to two b quarks.
Theoretical calculations of this process predict a branching fraction of 6.7–7.7 × 10–7.
LHCb has now made its first measurement of top quark production using Run-2 data collected in proton–proton collisions at the energy of 13 TeV.
The Higgs-to-two-photons decay played a crucial role in the discovery of the Higgs boson in 2012 owing to the excellent mass resolution and well-modelled backgrounds in this channel.
Tim Gershon of LHCb argues that apparently harmless academic discussions risk evolving into a negative outlook for the field.
In two new results, ATLAS presents strong evidence for the production of a single top quark in association with a Z boson.
No more than a few hundred tZq events and a dozen tttt events were expected after selection.
The coupling can be directly probed by measuring the rate of events in which a Higgs boson is produced in association with a pair of top quarks.
