Abstract: Probing Physics Beyond the Standard Model with Cosmological Phase Transition and Gravitational Waves Primordial gravitational waves from a first order cosmological phase transition has become a new cosmic frontier for probing physics beyond the standard model and can complement current direct searches at the energy and intensity frontier. Especially important is the possibility of a first order electroweak phase transition, which plays a  central role in generating the observed baryon asymmetry in the universe in electroweak baryogenesis. In this talk I will review recent developments of the theoretical modelling and numerical simulations of the gravitational wave production during a first order cosmological phase transition, and experimental searches of a stochastic background of gravitational waves. I will further show with examples that there generically exists a complementarity between collider and gravitational wave measurements in probing physics beyond the standard model.

Bio: 郭怀珂，目前研究的主要问题为暗物质、物质反物质不对称以及粒子物理中超出标准模型的新物理。尤其是利用引力波作为新的工具对上述问题进行探索，如宇宙相变过程中引力波的理论研究和LIGO探测器上的实验搜寻、其与对撞机上对新物理寻找的互补性研究，以及用引力波探测器探索各类暗物质的研究等。
