Revision as of 17:42, 25 July 2020 by 217.103.180.188 (talk)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)In theoretical particle physics, the non-commutative Standard Model (also known as Spectral Standard Model ), mainly due to the French mathematician Alain Connes, uses noncommutative geometry to devise an extension of the Standard Model to include a modified form of general relativity. This unification implies a few constraints on the parameters of the Standard Model. Under an additional assumption, known as the "big desert" hypothesis, one of these constraints determines the mass of the Higgs boson to be around 170 GeV, comfortably within the range of the Large Hadron Collider. Recent Tevatron experiments exclude a Higgs mass of 158 to 175 GeV at the 95% confidence level and recent experiments at CERN suggest a Higgs mass of between 125 GeV and 127 GeV. However, the previously computed Higgs mass was found to have an error, and more recent calculations are in line with the measured Higgs mass.
