摘要: It was proposed that the massive compact halo objects (MCHOs) would be produced during an earlier epoch of cosmology if density perturbations are between $3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ and 0.3. Then these can accrete dark matter particles onto them due to their high density. If is in form weakly interacting particles, MCHOs have a significant effect on evolution annihilation within them. Using WMAP-7 years data, we investigated constraints current abundance (${f}_{\mathrm{MCHOs}}$) formed ${e}^{+}{e}^{\ensuremath{-}}$ phase transition. We found $2\ensuremath{\sigma}$ constraint ${f}_{\mathrm{MCHOs}}\ensuremath{\lesssim}{10}^{\ensuremath{-}4}$ for masses range 1 GeV TeV.
