# Regarding the distribution of glue in the pion

@inproceedings{Chang2021RegardingTD, title={Regarding the distribution of glue in the pion}, author={Lei Chang and C. Roberts}, year={2021} }

Understanding why the scale of emergent hadron mass is obvious in the proton but hidden in the pion may rest on mapping the distribution functions (DFs) of all partons within the pion and comparing them with those in the proton; and since glue provides binding in quantum chromodynamics, the glue DF could play a special role. Producing reliable predictions for the proton’s DFs is difficult because the proton is a three valence-body bound-state problem. As sketched herein, the situation for the… Expand
