Single-wave solutions of the neutrino fast flavor system. Part II. Weak instabilities and their resonant behavior

Damiano F. G. Fiorillo, Georg G. Raffelt

Flavor instabilities in dense neutrino media trigger exponential growth of flavor waves, yet their nonlinear saturation remains poorly understood. We examine a simple proxy for thi…

Single-wave solutions of the neutrino fast flavor system. Part I. Mechanical properties

Damiano F. G. Fiorillo, Georg G. Raffelt

A dense neutrino plasma can exhibit collective flavor evolution caused by neutrino--neutrino refraction. Recently, a new class of exact nonlinear inhomogeneous solutions was discov…

Constraining the Higgs potential using multi-Higgs production

Jia-Le Ding, Zach Gillis, Ulrich Haisch +10

The Higgs self-couplings remain only weakly constrained by current Large Hadron Collider (LHC) measurements, leaving ample room for physics beyond the Standard Model that could mod…

Stripped-Envelope Supernovae for QCD Axion Detection

Francisco R. Candón, Damiano F. G. Fiorillo, Ángel Gil Muyor +3

QCD axions would be copiously produced in the proto-neutron star formed in a core-collapse supernova (SN). After escaping, they would convert into gamma rays in the Galactic magnet…

Muonic Boson Limits: Supernova Redux

Andrea Caputo, Georg Raffelt, Edoardo Vitagliano

We derive supernova (SN) bounds on muon-philic bosons, taking advantage of the recent emergence of muonic SN models. Our main innovations are to consider scalars in addition t…

Axion-photon conversion in transient compact stars: Systematics, constraints, and opportunities

Damiano F. G. Fiorillo, Ángel Gil Muyor, Hans-Thomas Janka +2

We study magnetic conversion of ultra-relativistic axion-like particles (ALPs) into photons in compact-star environments, focusing on the hot, transient conditions of core-collapse…
