Selfconsistent calculation of the Sommerfeld enhancement
A calculation of the Sommerfeld enhancement is presented and applied to the problem of swave nonrelativistic dark matter annihilation. The difference from previous computations in the literature is that the effect of the underlying shortrange scattering process is consistently included together with the longrange force in the effective QM Schrödinger problem. Our procedure satisfies partialwave unitarity where previous calculations fail. We provide analytic results for some potentials of phenomenological relevance.
