New calculations predicting the spatial distributions of the charges, momentum, and other properties of the quarks within protons found that the up quarks are more symmetrically distributed and spread over a smaller distance within the proton than the down quark. The results imply that these two types of quarks contribute differently to a proton’s properties.

Nuclear theorists examined this muon capture process to quantify theoretical uncertainty relevant for comparison with experimental data and to test predictions involving proton-proton fusion. The study supports ongoing efforts to enhance the accuracy of muon capture measurements and to apply the same theoretical framework to other processes.
