abstract
We present a new analysis of parton distributions of the proton. This incorporates a wide range of new data, an improved treatment of heavy flavours and a re-examination of prompt photon production. The new set (MRST) shows systematic differences from previous sets of partons which can be identified with particular features of the new data and with improvements in the analysis. We also investigate the sensitivities of the results to (i) the uncertainty in the determination of the gluon at large x, (ii) the value of alpha_S(M_Z^2) and (iii) the minimum Q^2 cut on the data that are included in the global fit.

Using NJL density-dependent quark masses in a light-front dressed-quark model, the paper predicts O(10–40%) medium modifications of GTMDs linked to quark OAM, spin, and spin–orbit correlation, and defines eA/eP GTMD ratios as nuclear-density probes.
