Left-Right Symmetry Model with Two Bidoublets and One Doublet Higgs Field for Electroweak Interaction

Abstract

We use the left-right symmetry model based on SU(2)_{L}xSU(2)_{R}xU(1)_{B-L} gauge group with two bidoublets and one doublet Higgs field for electroweak interaction. The lepton fields are represented as a doublet of SU(2)for both left and right fields. By using the pattern of symmetry breaking emerges as the minimum of the Higgs potential for a range of parameters, we show that the domination of the V-A over V+A interactions is natural at low energy. The symmetry breaking is the responsible mechanism for the up-down lepton doublet mass difference
