A fresh look on the limit on ultralight axion-like particles from SN1987A
Alexandre Payez
We revisit the limit on very light axion-like particles (ALPs) from the absence of gamma rays coincidental with the neutrino burst from SN1987A. We use updated supernova simulation…

Revisiting the SN1987A gamma-ray limit on ultralight axion-like particles
Alexandre Payez, Carmelo Evoli, Tobias Fischer +3
We revise the bound from the supernova SN1987A on the coupling of ultralight axion-like particles (ALPs) to photons. In a core-collapse supernova, ALPs would be emitted via the Pri…

New constraints on very light pseudoscalars
A. Payez, J. R. Cudell, D. Hutsemékers
Nearly massless axion-like particles are of interest for astrophysical observations, and some constraints on their parameter space do exist in the literature. Here, we propose to p…
