Investigating the gamma-ray burst from decaying MeV-scale axion-like particles produced in supernova explosions
Eike Müller, Francesca Calore, Pierluca Carenza +2
We investigate the characteristics of the gamma-ray signal following the decay of MeV-scale Axion-Like Particles (ALPs) coupled to photons which are produced in a Supernova (SN) ex…
Non-Gaussianity in rapid-turn multi-field inflation
Oksana Iarygina, M. C. David Marsh, Gustavo Salinas
We show that theories of inflation with multiple, rapidly turning fields can generate large amounts of non-Gaussianity. We consider a general theory with two fields, an arbitrary f…
On the applicability of the Landau-Zener formula to axion-photon conversion
Pierluca Carenza, M. C. David Marsh
Axions and photons resonantly interconvert in regions where the plasma frequency approximately equals the axion mass. This process is directly analogous to an avoided level crossin…
