Constraining axionlike particles using the distance-duality relation

arXiv:1610.06583 · doi:10.1103/PhysRevD.95.023005

Abstract

One of the fundamental results used in observational cosmology is the distance duality relation (DDR), which relates the luminosity distance, , with angular diameter distance, , at a given redshift . We employ the observed limits of this relation to constrain the coupling of axion like particles (ALPs) with photons. With our detailed ALP-photon mixing simulation in standard CDM universe and latest DDR limits observed in Holand \& Barros (2016) we limit the coupling constant for ALPs of mass eV. The DDR observations can provide very stringent constraint on ALPs mixing in future. Also any deviation in DDR can be conventionally explained as photons decaying to axions or vice-versa.
