In dark matter coannihilation scenarios,the Sommerfeld effect of coannihilators is usually important in the calculations of dark matter thermal relic *** to decays of coannihilators,two annihilating coannihilators can only approach each other from a finite initial *** conventional derivations of Sommerfeld factors essentially assume an infinite initial separation,Sommerfeld factors for a pair of annihilating coannihilators may be *** find that the Sommerfeld factor for a pair of coannihilators is less prominent than that obtained without considering *** of the Sommerfeld factor may result in a change of the dark matter thermal relic abundance well beyond the percent level.
