Probing primordial gravitational waves: Ali CMB Polarization Telescope. [PDF]

open access: yesNatl Sci Rev, 2019
In this paper, we will give a general introduction to the project of Ali CMB Polarization Telescope (AliCPT), which is a Sino-US joint project led by the Institute of High Energy Physics (IHEP) and has involved many different institutes in China.

Neutrino mass and leptogenesis in a hybrid seesaw model with a spontaneously broken CP

open access: yesJournal of High Energy Physics, 2023
We introduce a novel hybrid framework combining type I and type II seesaw models for neutrino mass where a complex vacuum expectation value of a singlet scalar field breaks CP spontaneously.

Leptogenesis in SO(10) models with A4 modular symmetry

open access: yesJournal of High Energy Physics, 2022
We study the prediction for leptogenesis in two renormalizable supersymmetric SO(10) × A 4 modular models in which the neutrino mass is dominantly generated by the type I seesaw mechanism. The evolution of the lepton asymmetries are described in terms of

New benchmark scenarios of electroweak baryogenesis in aligned two Higgs double models

open access: yesJournal of High Energy Physics, 2022
We discuss electroweak baryogenesis in aligned two Higgs doublet models. It is known that in this model the severe constraint from the experimental results for the electron electric dipole moment can be avoided by destructive interference among CP ...

Type II Seesaw leptogenesis

open access: yesJournal of High Energy Physics, 2022
The Type II Seesaw Mechanism provides a minimal framework to explain the neutrino masses involving the introduction of a single triplet Higgs to the Standard Model.

Doubly peaked induced stochastic gravitational wave background: testing baryogenesis from primordial black holes

open access: yesJournal of High Energy Physics, 2022
Hawking evaporation of primordial black holes (PBHs) can facilitate the generation of matter-antimatter asymmetry. We focus on ultra-low mass PBHs that briefly dominate the universe and evaporate before the big bang nucleosynthesis.

Interplay between dark matter and leptogenesis in a common framework

open access: yesJournal of High Energy Physics, 2023
We consider the interplay between dark matter and leptogenesis in a common framework, where three right-handed neutrinos, one fermionic dark matter and two singlet scalars are introduced into the Standard Model.

Cosmological CPT Violation, Baryon/Leptogenesis and CMB Polarization [PDF]

open access: yes, 2006
In this paper we study the cosmological CPT-violation and its implications in baryo/leptogenesis and CMB polarization. We propose specifically a variant of the models of gravitational leptogenesis.

Affleck-Dine baryo/leptogenesis with a gauged U(1)(B-L) [PDF]

open access: yes, 2001
We briefly review the present status of Affleck-Dine baryo/leptogenesis scenarios in the minimal supersymmetric standard model (MSSM) in the context of the gravity-mediated SUSY breaking, and show that there is a serious cosmological problem in the ...

Electroweak baryogenesis via top-charm mixing

open access: yesJournal of High Energy Physics, 2023
We investigate a scenario of electroweak baryogenesis in the two Higgs doublet model with quark flavor mixing. In general, off-diagonal components of quark Yukawa interactions with additional Higgs bosons are strongly constrained by the data for flavor ...
