The CTEQ/TEA machinery for measuring Parton Distribution Functions is used to obtain estimates and limits on non-perturabative ("intrinsic") charm quark contributions to the proton wave function.

The array of collider and fixed-target experiments either presently taking data or planned for the near future has renewed a focus on precise determinations of the proton's quark substructure as quantified by its parton distribution functions (PDFs). In this context, special focus has attached to the PDF of the charm quark, given its special relevance to, e.g., collider backgrounds and...

The discovery of extraterrestrial neutrinos in the $\sim$ 30 TeV -- PeV energy range by IceCube provides new constraints on high energy astrophysics. An important background to the signal are the prompt neutrinos which originate from the decay of charm hadrons produced by high energy cosmic-ray particles interacting in the Earth's atmosphere. It is conventional to use pQCD calculations of...

We present a new global QCD analysis of spin-dependent PDFs (SPDF)
and fragmentation functions (FF) performed by the JAM (Jefferson Lab
Angular Momentum) Collaboration, based on all available data on
inclusive spin structure functions from CERN, SLAC, DESY and JLab,
and all semi-inclusive hadron production data from electron-positron
annihilation experiments, including the most...
