The Large Hadron Collider\u2019s ATLAS Collaboration observes, for the first time, the coincident production of a photon and a top quark.<\/p>\n

In the ever-evolving landscape of particle physics, a field that explores the nature of the Universe\u2019s fundamental building blocks, nothing generates a buzz quite like a world\u2019s first. Such a first is exactly what CERN\u2019s ATLAS Collaboration has now achieved with its observation of the coincident production of single top quarks and photons in proton\u2013proton collisions at the Large Hadron Collider (LHC) [1<\/a>] (Fig. 1<\/a>). This discovery provides a unique window into the intricate nature of the so-called electroweak interaction of the top quark, the heaviest known fundamental particle.<\/p>\n

The standard model of particle physics defines the laws governing the behavior of elementary particles. Developed 50 years ago [2<\/a>, 3<\/a>], the model has\u2014to date\u2014withstood all experimental tests of its predictions. But the model isn\u2019t perfect. One of the model\u2019s biggest problems is a theoretical one and relates to how the Higgs boson gives mass to other fundamental particles. The mechanism by which the Higgs provides this mass is known as electroweak symmetry breaking, and while the standard model gives a reasonable description of the mechanism, exactly how electroweak symmetry breaking comes about remains a mystery.<\/p>\n","protected":false},"excerpt":{"rendered":"
