"The new analysis looks at when a B meson decays into another meson containing a strange quark, known as a kaon, as well as two muons. They found that the angle at which the final products emerge from the decay disagree with those predicted by the Standard Model."
"Rather than looking for new, heavy particles directly, LHCb looks indirectly for their subtle effects, including when they pop up fleetingly as 'virtual particles' that influence decays."
The Standard Model of particle physics is recognized as incomplete due to its inability to explain phenomena like dark matter. Recent findings from the Large Hadron Collider indicate a growing anomaly in B meson decays, where the angles of emerging particles deviate from Standard Model predictions. This anomaly, which has been accumulating evidence since 2015, suggests the presence of new physics through indirect observations of virtual particles influencing decay processes. The LHCb experiment focuses on these subtle effects to uncover deeper insights into particle interactions.
