26. Extended Scalar Sectors and Baryogenesis: The CP story

Jose Miguel No (IFT-UAM/CSIC)

22/09/2023, 13:30

I will give a personal perspective on the possibility of achieving EW baryogenesis in extensions of the SM, based on enhancing the CP violating sources in the early Universe as compared to the ones constrained by EDMs at present times.

54. Addressing the Gravitational Wave - Collider Inverse Problem

Van Que Tran (TDLI- Shanghai Jiao Tong University)

22/09/2023, 14:00

This talk is based on arXiv:2203.05889. Next generations of gravitational wave and future collider detectors can probe beyond the Standard Model theories that predict a strong first order electroweak phase transition. A combination of these two signals could be used to determine BSM scenarios and to measure relevant model parameters. In this talk, I will show a roadmap for addressing this...

6. Gravitational waves from phase transitions during inflation

Haipeng An (Tsinghua University)

22/09/2023, 14:30

The large excursion of the inflaton may trigger phase transitions in the spectator sector that couples to the inflaton field. Such phase transitions can produce gravitational waves. In this talk, I will discuss the properties of the gravitational waves produced in this way. I will discuss both first- and second-order phase transitions. The phase transitions during inflation can also produce...
