Abstract
The latest unsuccessful Higgs searches at LEP have pushed its mass well into the domain where significant signals can be expected from the LHC experiments. The most sensitive LHC Higgs signatures are reviewed and the discovery year is estimated as a function of the Higgs mass. Finally, we give some ideas about: ‘What might be known about the production and decays of a SM Higgs boson’ after 10 years of LHC?

Various observations, consistent with neutrino mixing, indicate that neutrinos have a nonzero mass. This contradicts the fundamentalistic interpretation of the SM, which demands for massless neutrinos [2]

The TEVATORN measurements of various 00123 decays and especially the 6-jet top signal demonstrate that many additional signatures can be exploited once the mass is known [18]
