ATLAS observes interaction between Higgs boson and top quark, the heaviest known elementary particle

The ATLAS Collaboration at CERN has announced the observation of Higgs bosons produced together with a top-quark pair. Observing this extremely rare process is a significant milestone for the field of High-Energy Physics. It allows physicists to test critical parameters of the Higgs mechanism in the Standard Model of particle physics.

Since 2011 the IFAE-ATLAS group has led searches for ttH production, focusing on the dominant Higgs boson decay mode into a bottom-antibottom-quark pair (H->bb)
