Description

In the previous decade, the topic of the nucleon's nonperturbative or $\mathit{i}\mathit{n}\mathit{t}\mathit{r}\mathit{i}\mathit{n}\mathit{s}\mathit{i}\mathit{c}$ charm content has enjoyed something of a renaissance, largely motivated by theoretical developments involving quark modelers and PDF-fitters. In this talk I will briefly describe the importance of intrinsic charm to various issues in high-energy phenomenology, and survey recent progress in constraining its overall normalization and contribution to the momentum sum rule of the nucleon. I end with the conclusion that progress on the side of calculation has now placed the onus on experiment to unambiguously resolve the proton's intrinsic charm component.
