Scientific paper

We point out that thermal relic abundance of dark matter is strongly altered by a non-perturbative effect called the Sommerfeld enhancement, when constituent particles of the dark matter are SU(2)L non-singlet and much heavier than the weak gauge bosons. Typical candidates are the heavy wino and higgsino. We investigate the non-perturbative effect on the relic abundance of dark matter for the wino as an example. We show that its thermal abundance is reduced by 50% compared to the perturbative result. The wino mass consistent with the observed dark matter abundance turns out to be 2.7 TeV
