The super-rare creation of three quantum particles of the forces (W bosons, Z bosons, photons) simultaneously allows a direct test of quantum interactions between the carriers of forces. This #CMSpaper measures this for the first time in the LHC Run 3 dataset (for WWZ production) and sets limits (uncertainties: 30-ish percent, using all data we have up to now) on what interactions are observed between these particles https://arxiv.org/abs/2505.20483
