Higgs boson - Wikipedia
WEBIn 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/c2 by CMS (2022) [36] and 125.11 ± 0.11 GeV/c2 by ATLAS (2023). It is the only particle that remains massive even at very high energies.
