The rest mass of Higgs boson is estimated to be close to

The Higgs boson is a fundamental particle in the Standard Model of particle physics. Experimental results from the Large Hadron Collider (LHC) at CERN, specifically from the ATLAS and CMS collaborations, have consistently measured its rest mass to be approximately 125 GeV [1]. In 2012, the discovery was announced with a mass around 125-126 GeV [1]. Subsequent precise measurements by the CMS collaboration refined this value to approximately 125.35 GeV with a very low margin of error. The Standard Model does not predict the mass of the Higgs boson itself, so it must be determined experimentally. Among the given options, 100 GeV is the closest estimate to the established value of 125 GeV, whereas 0.5 MeV (electron mass scale), 900 MeV (proton mass scale), and 1000 GeV are significantly different from the observed data.
