In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the data corresponding to the production of a 30-times larger number of Higgs bosons, we have...

The Higgs—boson mass in standard SU (2)× U (1) electroweak theory is obtained by requiring the one-loop effective potential to be an exact solution of the renormalization—group equation. Neglecting fermion couplings one gets m H =35 GeV....
The Higgs boson is a subatomic particle proposed by Peter Higgs in 1964, which is believed to be responsible for giving particles in the visible universe their mass. It was discovered in 2012 through experiments conducted at CERN using the Large Hadron Collider. ...
Still, it's hard to overestimate the importance of the Higgs boson and the Higgs field in general, as without this aspect of nature no particles would have mass. That means nostars, no planets, and no us — something which may help warrant its hyperbolic nickname. ...
and assuming that the ratio of the quartic scalar coupling to the U (1) gauge coupling is bounded in the ultraviolet limit, we obtain an upper bound of 130 GeV on the mass of the Higgs boson and a prediction of 43 GeV in the special case where the quartic scalar coupling is assumed ...
In the minimal supersymmetric model, the tree-level mass of the lightest CP-even Higgs boson (h) is zero if the parameters of the potential are chosen such that the minimum lies along a line corresponding to equal vacuum expectation values for the two Higgs doublets. In this case, the mass...
We calculate the Higgs-boson mass spectrum and the corresponding mixing of the Higgs states in the Minimal Supersymmetric Standard Model (MSSM). We assume
The Higgs boson, recently discovered with a mass of 125.7 GeV is known to mediate the masses of elementary particles, but only 2% of the mass of the nucleon. Extending a previous investigation (Schumacher, Ann. Phys. (Berlin) 526, 215 (2014)) and including the strange-quark sector, hadron...
The Higgs Boson 希格斯玻色子|上帝粒子 Right after the Big Bang, starting from zero, the energy density was so high that it exceeded the vacuum expectation value for the Higgs field, resulting in a valid symmetrical standard model without the presence of mass at all. The Higgs field grew as...
