DOI: 10.1007/jhep12(2025)025
Abstract: Long-range attractive interactions between dark matter particles can significantly enhance their annihilation, particularly at low velocities. This “Sommerfeld enhancement” is typically computed by evaluating the deformation of the two-particle wavefunction due to the long-range potential,… read more here.

DOI: 10.1038/s41557-022-00896-2
Abstract: One of the most important parameters in a collision is the ‘miss distance’ or impact parameter, which in quantum mechanics is described by quantized partial waves. Usually, the collision outcome is the result of unavoidable… read more here.
