Spectrum of background x-rays from moduli dark matter
Spectrum of background x-rays from moduli dark matter
We examine the x-ray spectrum from the decay of dark-matter moduli with mass $\ensuremath{\sim}100\mathrm{keV},$ in particular, paying attention to the line spectrum from the moduli trapped in the halo of our galaxy. It is found that with the energy resolution of the current experiments $(\ensuremath{\sim}10%)$ the line intensity is about …
