Observing this decay mode and measuring its rate is mandatory to confirm (or not) the mass generation for fermions via Yukawa interactions, as predicted in the SM.
The conference brought together more than 100 researchers from 18 countries to discuss the latest results in precision calculations for particle physics at colliders.
Some 450 researchers from around the world headed to historic Bologna to attend the sixth Large Hadron Collider Physics conference.
New results released by the ATLAS collaboration firmly establish and measure these so-called Yukawa couplings to third-generation fermions.
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.
