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.
