Baryogenesis and Asymmetric Dark Matter from The Left-Right Mirror Symmetric Model

The paper suggests a left-right mirror symmetric model to account for the baryogenesis and asymmetric dark matter. The model can simultaneously accommodate the standard model, neutrino physics, matter-antimatter asymmetry and dark matter. In particular, it naturally and elegantly explains the origin of the baryon and dark matter asymmetries, and clearly gives the close interrelations of them. In addition, the model predicts a number of interesting results, e.g. the cold dark matter neutrino mass is $3.1$ times the proton mass. It is also feasible and promising to test the model in future experiments.Comment: 24 pages, 4 figures. arXiv admin note: text overlap with arXiv:1309.195

Neutrino Mass, Leptogenesis, and Dark Matter from The Dark Sector with U(1)DU(1)_{D}

I suggest a new extension of the SM by introducing a dark sector which has several new particles and a local $U(1)_{D}$ symmetry. The dark particles bring about the new and interesting physics beyond the SM. The model can generate the tiny neutrino mass by a hybrid see-saw mechanism, achieve the leptogenesis at the TeV scale, and account for the cold dark matter. All of the three things collectively arise from the dark sector. In particular, it is very feasible to test the model predictions and probe the dark sector in near future experiments.Comment: 18 pages, 4 figures, to be published by JHEP. arXiv admin note: text overlap with arXiv:1706.0723
