Topological Defects in the Left-Right Symmetric Model and their Relevance to Cosmology
It is shown that the minimal left-right symmetric model admits cosmic string
and domain wall solutions. The cosmic strings arise when the SU(2)_R is broken
and can either be destabilized at the electroweak scale or remain stable
through the subsequent breakdown to U(1)_{EM}. The strings carry zero modes of
the neutrino fields. Two distinct domain wall configurations exist above the
electroweak phase transition and disappear after that. Thier destablization
provides new sources of non-equilibrium effects below the electroweak scale
which is relevant to baryogenesis.Comment: 29 pages, LaTex file with 6 postscript figure
