Abstract
We briefly discuss some of the developments since the publication of the MMHT14 parton distributions. In particular we explore the impact of recent LHC data for W±, Z and tt¯production, and perform a preliminary new analysis including these data. In this re-fit (which we tentatively call ‘MMHT16’) there are few changes of significance in the central values of the PDFs, but some data reduce the uncertainties, mainly in the strange and valence quark distributions. We find that an extended d¯− u¯ parametrization only leads to minor changes, with the difference going to zero as x → 0. We comment on the determination of the photon PDF.
