Title: Festina-Lente bound, Higgs vacuum structure and more
Abstract: The recently suggested Festina-Lente (FL) bound provides a lower bound on the masses of U(1) charged particles in terms of the positive vacuum energy. Since the charged particle masses in the Standard Model (SM) are generated by the Higgs mechanism, the FL bound provides a testbed of consistent Higgs potentials in the...
Title: Manifesting hidden dynamics of a sub-component dark matter
Abstract: A distinctive cosmological dynamics of a sub-component dark matter will be discussed. The thermal evolution of the sub-component is significantly affected by the sizable self-scattering and the required annihilation cross section of the sub-component sharply increases as we consider a smaller relative abundance...
Title: Numerical studies for black hole encounters
Abstract: Black hole binary mergers have been playing an important role in exploring a new world seen by gravitational waves. Gravitational wave events from non-circular mergers or black hole encounters in general are expected to be observed as the sensitivity of current detectors are improved at low frequencies. In this talk, we present...
