Astrophysical Constraints on Dark Matter Annihilation with Sommerfeld Enhancement Speaker(s): Jesus Zavala Franco
Abstract: Dark matter models with an annihilation cross section enhanced by a Sommerfeld mechanism have been proposed in the past years to explain a number of observed anomalies, such as the excess of high energy positrons in cosmic rays reported by PAMELA. However, this enhancement can not be arbitrarily lar... read more

Astrophysical constraints on dark matter annihilation with Sommerfeld enhancement Speaker(s): Jesus Zavala Franco
Abstract: In recent years, a number of observations have highlighted anomalies that might be explained by invoking dark matter annihilation. The excess of high energy positrons in cosmic rays reported by the PAMELA experiment is only one of the most prominent examples of such anomalies. Models where dark matt... read more
