Topological aspects of chiral anomaly, origin of mass and electroweak theory

It is here shown that the topological property of a fermion which gives ris e to the fermion number and is related to chiral anomaly may be taken to le ad to weak interaction gauge bosons when currents are written in chiral for m. The gauge bosons attain mass topologically through the generation of int ernal helicities and thus no Higgs scalar is needed to have spontaneous sym metry breaking. Moreover the group structure SU(2) x U(I) is inbuilt here f or electroweak unification. The Weinberg angle gets a physical meaning and strangeness changing neutral lepton current interaction is automatically fo rbidden. This formalism also suggests that at very high temperature, weak i nteraction will be of long range in nature.
