Abstract
There are indications for the Weinberg-Salam model being an effective theory only. This would imply a relation between the scale (Λcut) before which new physics should be observed and the Higgs meson massm H. The relation Λcut=Λcut(m H ) is studied in an approximate, but nonperturbative way. Form H m w≳10, Λcut is of the order of the Higgs meson mass itself (i.e. this is an upper bound), while form H m W≲6, Λcut can be very large and no practically interesting constraint emerges.
