From Live Science, June 4, 2018: The Higgs boson appeared again at the world’s largest atom smasher — this time, alongside a top quark and an antitop quark, the heaviest known fundamental particles.

Earlier today the CMS paper titled “Observation of ttH Production” was accepted for publication by Physical Review Letters. In this article, the CMS collaboration presented the first observation of the coupling between the Higgs boson and the top quark. The strength of this coupling as measured by CMS is consistent with the Standard Model expectation. This observation connects for the first time directly the two heaviest elementary particles of the Standard Model: the top quark, which was discovered in 1995… More »

It doesn’t seem like collisions of particles with no mass should be able to produce the “mass-giving” boson, the Higgs. But every other second at the LHC, they do.
