Physicists spotted rare W boson trios at the Large Hadron Collider
The ‘WWW’ events appeared in the ATLAS experiment
![A candidate WWW event is visualized. On a black backdrop, one part of the image shows a reddish burst of energy with a green ring surrounded by a yellow ring. Another part of the image shows a similar event, but witih red, green and white lines illustrating particles' tracks, and surrounded by additional light in various colors.](https://i0.wp.com/www.sciencenews.org/wp-content/uploads/2022/08/081122_EC_WWW_feat.jpg?fit=1030%2C580&ssl=1)
Physicists detected triplets of W bosons in the ATLAS experiment. One candidate WWW event is shown in two different views in this visualization, in which the W bosons decay into other particles (whose reconstructed tracks are illustrated by colored lines).
