In 2018, the ATLAS and CMS Collaborations at CERN announced the observation of the production of the Higgs boson in association with a top-quark pair, known as "ttH" production. This result was the first observation of the ...

Light-by-light scattering is a very rare phenomenon in which two photons interact, producing another pair of photons. This process was among the earliest predictions of quantum electrodynamics (QED), the quantum theory of ...

Could a Grand Unified Theory resolve the remaining mysteries of the Standard Model? If verified, it would provide an elegant description of the unification of Standard Model forces at very high energies, and might even explain ...

The Higgs boson, discovered at the Large Hadron Collider (LHC) in 2012, has a singular role in the Standard Model of particle physics. Most notable is the Higgs boson's affinity to mass, which can be likened to the electric ...

The top quark is a unique particle due to its phenomenally high mass. It decays in less than 10 to -24 seconds, before it has time to interact with any other particles. Therefore, many of its quantum numbers, such as its ...
