Effects of the parityodd singlet on the N=1 supergravity theory within the leftright symmetric model
Abstract
We study the N=1 supergravity theory within the leftright symmetric model, based on the gauge symmetry SU(2)_{L}×SU(2)_{R}×U(1)_{BL}, when the parityodd singlet field is added, in addition to the minimal set of Higgs fields. This model allows for a vacuum solution with the hierarchy ratio η = (m_{WR/mWL) >1}. Also, the gravitino mass is likely to set the scale of m_{WL} rather than the one of mW_{R}. These features of the presented model should be contrasted with the results of the leftright symmetric model with the minimal set of Higgs fields, where η < O(10) and the gravitino mass naturally sets the scale of mW_{R}.
