Observation of production of three massive gauge bosons
The three massive gauge boson VVV (V = W, Z) production at the LHC is interesting because measurements of such processes can probe the interactions between massive bosons including the Higgs. Up until recently, such measurements have remained elusive because of low production cross sections. This talk will discuss the recent CMS result of first observation (5.7 sigma) of combined VVV production at the CERN LHC and evidences for WWW (3.3 sigma) and WWZ (3.4 sigma) productions individually. Finally, I will briefly discuss the future of the physics program of the rare multi-boson processes.
