In May 2023, scientists at CERN's Large Hadron Collider (LHC) announced the

first evidence of the Higgs boson decaying into a Z boson and a photon. 

This is a rare process, and its observation could provide indirect evidence of 

particles beyond those predicted by the Standard Model of particle physics. 

The Higgs boson is a fundamental particle that gives other particles their mass.  

It was first theorized in the 1960s, but it was not until 2012 that it was finally detected at the LHC.   

The Higgs boson is a very important particle, and 

its discovery has helped to confirm the Standard Model of particle physics. 

The Standard Model is a theory that describes the fundamental particles and forces of nature. 

It is a very successful theory, but it is not complete.
