16:14:00	 From Keping Xie : Hi Alessandro, as Maria pointed out, the da included in the CT18fit are not sensitive the the intrinsic charm PDF. However, the recent LHCb measurement of Z+charm production indicate the intrinsic charm, which we are working on.
16:16:13	 From Alessandro Tricoli : Thank you. If you have the arXiv link to this paper will be useful to see the level of sensitivity

16:20:37	 From Tim Hobbs : Hi Alessandro: in addition to the comments made by Maria and Keping, I would just note that measuring the proton's charm structure function at the EIC (a la the EMC 1983 result) should have quite clean sensitivity to any nonperturbative charm component, assuming the normalization is nonzero..

16:22:05	 From Sridhara Dasu : BTW - we should encourage our students and postdocs to attend these meetings. They should hear these excellent talks and participate in Snowmass affairs throughout this year. Lest, I am afraid lack of participation will be interpreted negatively by the rest of the community.
16:23:43	 From Alessandro Tricoli : Thank you Keping, the high rapidity bin in Z+c byLHCb is indeed very interesting.
16:46:18	 From maria vittoria : I agree!
