Dark matter, baryogenesis and inflation in BSM particle theories

该项目将研究粒子理论的新发展，以确定它们对宇宙学的影响，特别关注它们与暴胀的兼容性以及它们对包括暗物质和重子密度在内的可观测结果的影响。最初的项目将集中在标准模型的轴子和类轴子粒子（ALPs）扩展上。它将在最小KSVZ轴子模型的背景下研究标准模型希格斯势的亚稳态。它还将研究希格斯-轴子系统在暴胀期间和之后的演变。该项目随后将继续研究其他ALP和BSM粒子理论的宇宙学。

The project will investigate new developments in particle theory to determine their impact on cosmology, with particular focus on their compatibility with inflation and their consequences for observables including the dark matter and baryon densities. The initial project will focus on axions and axion-like particles (ALPs) extensions of the Standard Model. It will investigate the metastability of the Standard Model Higgs potential in the context of a minimal KSVZ axion model. It will also investigate the evolution of the Higgs-axion system during and after inflation. The project will later move on to investigate the cosmology of other ALP and BSM particle theories.
