Low-Frequency Gravitational Bremsstrahlung and Memory in a Medium
Diego Blas, Silvia Gasparotto, Hitoshi Murayama +2
Gravitational radiation from the early Universe offers a powerful window into physics beyond the Standard Model (SM). In this paper, we investigate the low-frequency tail of gravit…
Minimal Proton-Mass Dark Matter
Majed Khalaf, Eric Kuflik, Alessandro Lenoci +2
We present a minimal dark matter scenario: a single complex scalar carrying baryon and lepton number, with no new exact stabilizing symmetry. Its leading interaction is a dimension…
Observing Leptogenesis in Action with Gravitational Waves
Hitoshi Murayama, Bea Noether, Jan Schütte-Engel
Leptogenesis is arguably the best motivated theory of baryogenesis given the discovery of finite neutrino masses, yet its experimental test is elusive given its high energy scale.…
Small Neutrino Masses from Supersymmetry Breaking
Nima Arkani-Hamed, Lawrence Hall, Hitoshi Murayama +2
An alternative to the conventional see-saw mechanism is proposed to explain the origin of small neutrino masses in supersymmetric theories. The masses and couplings of the right-ha…
