CMS probes non-standard Higgs decays to ττ
Observing the Higgs via its decays into pairs of fermions further tests the predictions of the Standard Model.

ATLAS makes precision measurement of W mass
A precise measurement of the mass of the W boson, which was discovered at CERN in 1983, is vital because it is closely related to the masses of the top quark and the Higgs boson.

ATLAS spots light-by-light scattering
Heisenberg and his student Euler realised that photons may scatter off of each other through a quantum-loop process involving virtual electron and positron pairs.

Studies of electroweak-boson production by CMS
It is quite improbable for two colliding protons to produce a W or Z electroweak gauge boson. Producing two or more W or Z bosons in the same collision is even less likely.

ATLAS homes in on Higgs-quark couplings
The two heaviest quarks, the bottom and top, are particularly interesting because they have the largest couplings to the Higgs boson.

ATLAS observes single top-quarks at 13 TeV
ATLAS has recently measured the total cross-sections of single top-quark and top-antiquark production via the t-channel exchange of virtual W bosons.
