Constraining the pion distribution amplitude using Drell-Yan reactions on a proton

Using a reaction model that incorporates pion bound state effects and continuum results for proton parton distributions and the pion distribution amplitude, φπ, we deliver parameter-free predictions for the μ+ angular distributions in πN→μ+μ−X reactions on both unpolarised and polarised targets. The...
