A light Higgs Boson would invite Supersymmmetry | | John Ellis

6 Dec 2000 | | Journal: | Phys.Lett. B506 (2001) 331-336 | | Subject: | hep-ph | | Affiliation: | CERN) and Douglas Ross (CERN and Southampton | | Abstract: | If the Higgs boson weighs about 115 GeV, the effective potential of the Standard Model becomes unstable above a scale of about 10^6 GeV. This instability may be rectified only by new bosonic particles such as stop squarks. However, avoiding the instability requires fine-tuning of the model couplings, in particular if the theory is not to become non-perturbative before the Planck scale. Such fine-tuning is automatic in a supersymmetric model, but is lost if there are no Higgsinos. A light Higgs boson would be prima facie evidence for supersymmetry in the top-quark and Higgs sectors. | | Source: | arXiv, hep-ph/0012067 | | Services: | Forum | Review | PDF | Favorites | |
