Baryon number freeze-out in the Standard Model, precisely
Cristina Benso, Dietrich Bödeker, Kohei Kamada +4
Weak sphaleron transitions turn a lepton asymmetry of the Standard Model plasma in the early Universe into a baryon asymmetry, conserving baryon-minus-lepton number and its i…
High-sensitivity Ultralight Dark Matter detector: Parametrically Amplified Casimir Devices
Muping Chen, Hideo Iizuka, Kyohei Mukaida +2
We propose the use of sphere-and-plate Casimir force measurement setups to detect ultralight vector dark matter. We demonstrate that sub-picometer signals can be parametrically amp…
Gravitational Waves from Reheating beyond Instantaneous Thermalization
Kyohei Mukaida, Tenta Tsuji
We study gravitational-wave production during perturbative reheating without assuming instantaneous thermalization of the inflaton decay products. The injected energetic particles…
Revisiting unitarity of single scalar field with non-minimal coupling
Minxi He, Muzi Hong, Kyohei Mukaida +1
We have investigated the unitarity violation scale of a non-minimally coupled scalar field with quartic self-coupling. This model is widely studied in the literature but the estima…
Magnetic Helicity, Magnetic Monopoles, and Higgs Winding
Hajime Fukuda, Yuta Hamada, Kohei Kamada +2
Changes in magnetic helicity are often discussed across a variety of fields, from condensed matter physics to early universe cosmology. It is frequently stated that the helicity ch…
Revisiting constraints on magnetogenesis from baryon asymmetry
Yuta Hamada, Kyohei Mukaida, Fumio Uchida
Magnetic fields in the universe potentially serve as a messenger of primordial physics. The observationally suggested intergalactic magnetic fields may be a relic of helical primor…
