Jean Orloff (LPC-Clermont)
TL;DR
This paper calculates the annihilation cross section of light scalar dark matter particles into photons and examines the potential for detecting the resulting gamma-ray line as a signature of dark matter.
Contribution
It provides the first detailed computation of the gamma-ray line signal from light scalar dark matter annihilation.
Findings
The annihilation cross section into two photons is quantified.
The detectability of the gamma-ray line is assessed.
Implications for dark matter searches are discussed.
Abstract
We compute the pair annihilation cross section of light dark matter scalar particles into two photons, and discuss the detectability of the monochromatic line associated with these annihilations.
