In the Standard Model, the Higgs boson is a massive scalar boson whose mass must be found experimentally. Its mass has been determined to be 125.35 ± 0.15 GeV/ c 2 by CMS (2022) [ 35 ] and 125.11 ± 0.11 GeV/ c 2 by ATLAS (2023).
The search for the Higgs boson was a 40-year effort by physicists to prove the existence or non-existence of the Higgs boson, first theorised in the 1960s.The Higgs boson was the last unobserved fundamental particle in the Standard Model of particle physics, and its discovery was described as being the "ultimate verification" of the Standard Model.

The 2012 discovery of the Higgs boson is widely considered one of the great triumphs of modern physics. This is largely because it confirmed the existence of the Higgs field—a field much like ...
This Higgs mechanism predicted the existence of a new particle, the Higgs boson, the detection of which became one of the great goals of physics. [11] [12] In 2012, CERN announced the discovery of the Higgs boson at the Large Hadron Collider. [13]
Higgs, an emeritus professor at Edinburgh University, won a Nobel prize and a host of other plaudits for his work on what became known as the Higgs boson, showing how it gave the universe its shape.

Antihelium-4 produced and measured by the STAR detector; the first particle to be discovered by the experiment 2012 A particle exhibiting most of the predicted characteristics of the Higgs boson discovered by researchers conducting the Compact Muon Solenoid and ATLAS experiments at CERN's Large Hadron Collider [39]
The observed properties were consistent with the Higgs boson, but scientists were cautious as to whether it is formally identified as actually being the Higgs boson, pending further analysis. [149] On 14 March 2013, CERN announced confirmation that the observed particle was indeed the predicted Higgs boson.
