Weak interactions at high energies

It remains unclear what the meaning of the parameter Λ is and whether it is connected to the value of the mass of the intermediate boson. However, the necessity of using quite low values for Λ is an indication that not only at several hundred GeV, but already at energies of a few GeV an unexpected behaviour of the weak interaction should be present. This makes us hoping that already the next generation of neutrino experiments should yield new unexpected results on weak interactions. If one follows the general opinion that the mass of a particle is somehow generated by the interactions of the particle, and if one assumes that W-mesons exist with high mass, one has to wonder which interaction may be able to produce the high W-mass. In order to explain this, Marshak and Coworkers have considered the hypothesis that besides the weak interaction (4) the W-mesons have strong interactions among themselves [24]. It is interesting to observe that assuming strong interactions of the W's one gets into much less difficulties than one might expect at first sight. Possibly such strong interactions which are intimately connected to the weak interactions are able to provide the cut-off of the intermediate momenta in the KL→μ+ + μ− and KL - Ks-mass difference problems which we described schematically by the parameter Λ.
