A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

Roger Jones receives funding from STFC. I am a member of the ATLAS Collaboration As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is ...
