Featured Research: New Rare Pairs of Heavy Friends in ATLAS

Observing rare productions of heavy elementary particles can provide fresh insight into the Standard Model of particle physics. In a new result first presented by OU postdoc Muhammad Alhroob, the ATLAS Experiment presents strong evidence for the production of a single top quark in association with a Z boson.

The high proton–proton collision energy and rate of the Large Hadron Collider (LHC) makes it possible to produce the heaviest elementary particles, such as the top quark — which is about 175 times heavier than a proton…
