Abstract:
Beyond the Standard Model (BSM) theory can lead to a first-order electroweak phase transition (EWPT) with several associated theoretical and phenomenological implications. Such a phase transition could provide the necessary preconditions for the generation of the observed baryon asymmetry via electroweak baryogenesis and sources for potential observable gravitational wave (GW) signal at next-generation detectors such as LISA. BSM can also lead to various high energy collider observables at the present and future detectors.
In this talk, I will present a roadmap for analyzing the interplay between hypothetical future collider observations and the detection of a GW signal produced by a strong first order EWPT in BSM theories. I will discuss the state-of-the-art methods in computation of the thermodynamics, particularly, a combination of a dimensionally reduced, three-dimensional effective field theory and results of both perturbation theory and non-perturbative lattice simulations. I will show the results of applying these methods to the real scalar triplet extension of the SM. I will illustrate how a combination of direct and indirect measurements of the new scalar properties, in combination with the presence or absence of a GW detection, could test the model and identify the values of the model parameters.
Biography:
I am currently a platform post-doctor at TDLI. I have obtained my bachelor in Vietnam (2013) and my PhD degree in Taiwan (2018). I was a postdoc at Nanjing University (from 2018 to 2021). My research interest ranges from the low energy process phenomenology, Higgs physics, and long-lived particle searches at the LHC, dark matter physics, and electroweak phase transition in the early universe.
