Warwick physicist helps achieve observation of rare particle interaction
An international analysis team within the ATLAS collaboration, led by a scientist from the University of Warwick, has observed WWγ production — a rare process where two W bosons and a photon are produced together. This discovery provides new insight into the electroweak force, one of the fundamental forces governing particle interactions.
A paperLink opens in a new window titled “Observation of WWγ production in proton–proton collisions at √s = 13 TeV with the ATLAS detector and constraints on anomalous quartic gauge-boson couplings” has been published in Physics Letters B. The study reports the first ATLAS observation of this rare phenomenon, marking a significant step forward in testing the predictions of the Standard Model of particle physics.
Dr Muhammad Alhroob, a Research Fellow in the Department of Physics at the University of Warwick, has led the analysis team within the ATLAS collaboration for the past five years.
Dr Alhroob said: “This rare process observation is a milestone, as it confirms the electroweak predictions of the Standard Model of particle physics. Observing WWγ production for the first time strengthens our understanding of how fundamental particles interact and helps us search for signs of new physics beyond the Standard Model.”
The ATLAS collaboration brings together thousands of scientists and engineers from across the globe, united in their mission to explore the fundamental laws of nature.
