Title First-Order Phase Transitions in the Early Universe: Implications for Baryogenesis and Gravitational Wave Astronomy
Abstract This talk explores recent advances in the study of first-order phase transitions hypothesized in a wide range of particle physics models and their profound implications for cosmology. These transitions are pivotal for explaining the baryon asymmetry observed in the universe and for the generation of a stochastic gravitational wave background with signatures potentially detectable by the next generation of gravitational wave observatories. With the rising capabilities of gravitational wave astronomy, new opportunities arise to investigate the interplay between particle collider experiments and gravitational wave detection in probing the scalar sector of the Standard Model. This interdisciplinary approach holds promise for unraveling key mysteries of the early universe and guiding the search for physics beyond the Standard Model.
