Mirror left–right symmetry

Abstract: We propose a novel left–right symmetric model where the standard model fermion and Higgs fields are doublets or singlets while their mirror partners are doublets or singlets. The scalar fields also include a real singlet for dark matter and two triplets for seesaw. The mixing between the standard model and mirror fermions is forbidden by a discrete symmetry. The mirror charged fermions can decay into their standard model partners with the dark-matter scalar while the mirror neutrinos can decay into the mirror charged fermions through the right-handed gauge interactions. Our model can have new implications on the strong CP problem, leptogenesis, collider phenomenology and dark matter detection. [Copyright &y& Elsevier]
