Lepton sourced baryon asymmetry in the fourth generation model
Hsiang-nan Li
We demonstrate that the observed baryon asymmetry in the Universe can be accommodated in the extended Standard Model with sequential fourth generation fermions (SM4). We first cons…
LHC di-dijet excesses as signals of fourth-generation tetraquarks
Hsiang-nan Li
We postulate that the excesses of di-dijet events observed at the LHC are attributed to the production of four fourth-generation quarks with a mass TeV at fe…
Light baryon static properties in dispersive approach
Shuge Zeng, Hsiang-nan Li, Fanrong Xu
We extend our dispersive analyses on meson static properties to those of light baryons. The formalism treats the dispersion relation, which a baryonic correlation function obeys, a…
Realization of electroweak baryogenesis by fourth generation fermions
Hsiang-nan Li
We demonstrate that the electroweak baryogenesis can be realized in the extended Standard Model with sequential fourth generation fermions (SM4). The solution to the coupled Dyson-…
Dispersive determination of the fourth generation lepton masses
Hsiang-nan Li
We continue our previous determination of the masses of the sequential fourth generation quarks in an extension of the Standard Model, and predict the mass () of the fou…
Understanding small neutrino mass and its implication
Hsiang-nan Li
We have derived previously the relations between the neutrino masses and mixing angles in a dispersive analysis on the mixing of neutral leptonic states. The only involved assumpti…
