dc.descriptionWe show how easy it is to get the Sommerfeld enhancement for a Yukawa potential, for definite partial waves, beyond the S wave analyzed in previous literature. In particular, we report results for the P wave (for which there is a resonant pattern and the enhancement can be of several orders of magnitude even far from the resonance) that could be relevant for the analysis of experimental cosmic rays data possibly signaling the annihilation of dark matter particles.
