Cosmology

We consider weakly interacting massive particle (WIMP) dark matter in a Parity solution to the strong CP problem. The WIMP …

新论文介绍：相变bubble的碰撞可以产生新粒子，从而成为新的引力波源。

Paper introduce: Primordial black holes can play a role as a factory to produce new BSM particles

I work on experimental and cosmological searches of dark sector mediators.

Neutrinos are often considered as a portal to new physics beyond the Standard Model (SM) and might possess phenomenologically …

Electroweak (-like) phase transition is expected to happen in the early universe, given the well-known spontaneous gauge symmetry breaking. This phase transition, if of first order, can provide the necessary out-of-equilbrium condition for baryogenesis. Such a phase transition can happen for the SM electroweak symmetry breaking, or any other similar symmetry breaking in BSM gauge group extensions. This project investigates possibilities to achieve electroweak (-like) baryogenesis in different models.

A type of models that can solve the strong CP problem, with large potential to explain the origin of matter-antimatter asymmetry and provide dark matter candidate.
