Energy and momentum dependence of the soft-axion interaction rate
Killian Bouzoud, Jacopo Ghiglieri, M. Laine +1
Axions coupled to thermal non-Abelian gauge fields may have cosmological significance. As the heat bath defines a frame, its influence depends separately on energy and momentum. A…

Thermal axion production at hard and soft momenta
Killian Bouzoud, Jacopo Ghiglieri
Hot axions, thermally produced in the Early Universe, would contribute to dark radiation and are thus subject to present and future constraints from . In this paper we…

New Constraint for Isotropic Lorentz Violation from LHC Data
David Amram, Killian Bouzoud, Nicolas Chanon +3
New calculations for the kinematics of photon decay to fermions in vacuo under an isotropic violation of Lorentz invariance (LV), parameterized by the Standard-Model Extension (SME…
