ATLAS reports direct evidence for Higgs–top coupling
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.

CMS sees Higgs boson decaying to b-quarks
The Higgs boson decays to a pair of b quarks is by far the most frequent decay channel, however the signal is overwhelmed by QCD production.

ATLAS experiment makes precision measurement of top-quark mass
While only retaining 40% of the events, the total uncertainty is improved by 19%, leading to a top-quark mass of 172.08±0.91 GeV.
