Abstract

It is suggested that the Higgs boson may have a branching ratio into the mode suppressed by several orders of magnitude compared with conventional predictions and in addition some small but detectable flavour-violating modes such as and . The suggestion is based on a scheme proposed and tested earlier for explaining the mixing pattern and mass hierarchy of fermions in terms of a rotating mass matrix. If confirmed, the effects would cast new light on the geometric origin of fermion generations and of the Higgs field itself.
