Probing SMEFT at Belle II with displaced dilepton vertices

Patrick D. Bolton, Fabian Esser, Lukáš Gráf +3

The existence of right-handed (RH) neutrinos is strongly motivated by the observation of small neutrino masses and as a means to shed light on the origin of parity violation in the…

Low-scale seesaw with flavour and CP symmetries $\unicode{x2013}$ from colliders to leptogenesis

Marco Drewes, Yannis Georis, Claudia Hagedorn +1

We consider an extension of the Standard Model with three right-handed neutrinos, endowed with a flavour symmetry , or , , and CP.…

Upper Bound on Thermal Gravitational Wave Backgrounds from Hidden Sectors

Marco Drewes, Yannis Georis, Juraj Klaric +1

Hot viscous plasmas unavoidably emit a gravitational wave background, similar to electromagnetic black body radiation. We study the contribution from hidden particles to the diffus…

Feebly Interacting Particles: FIPs 2022 workshop report

C. Antel, M. Battaglieri, J. Beacham +75

Particle physics today faces the challenge of explaining the mystery of dark matter, the origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the a…

Non-perturbative production of fermionic dark matter from fast preheating

Juraj Klaric, Andrey Shkerin, Georgios Vacalis

We investigate non-perturbative production of fermionic dark matter in the early universe. We study analytically the gravitational production mechanism accompanied by the coupling…
