    • Leptogenesis with left-right domain walls 

      YAJNIK, UA; CLINE, J; RABIKUMAR, M (INDIAN ACADEMY SCIENCES, 2004)
      The presence of domain walls separating regions of unbroken SU(2)(L) and SU(2)(R) is shown to provide necessary conditions for leptogenesis which converts later to the observed baryon asymmetry., The strength of lepton ...
    • Transient domain walls and lepton asymmetry in the left-right symmetric model 

      CLINE, JM; YAJNIK, UA; NAYAK, SN; RABIKUMAR, M (AMERICAN PHYSICAL SOC, 2002)
      It is shown that the dynamics of domain walls in left-right symmetric models, separating respective regions of unbroken SU(2)(L) and SU(2)(R) in the early universe, can give rise to baryogenesis via leptogenesis. Neutrinos ...
