We present an updated global analysis of nuclear PDFs, EPPS21. As main new constraints on our fit, we include LHC proton-lead 5 TeV double-differential dijet and D-meson data, and 8 TeV W$^\pm$ data. These measurements are found to give a consistent picture of small-x shadowing and mid-x antishadowing of nuclear gluons and significantly reduce the nuclear-PDF uncertainties. In addition, we...
In this contribution, an overview of the most recent measurements to constrain nuclear parton distribution functions at the LHC will be made.
Multi-parton distributions are the non-perturbative quantities needed to make predictions for multiple scattering rates. These are poorly constrained from theory and data, and must be modelled. For double parton scattering, some important theoretical constraints on the relevant distributions were derived in 2009: the momentum and number sum rules. Here we derive the corresponding sum rules for...
This talk gives an overview of the latest results of hadronisation studies at the LHC. The results will be discussed in comparison with various different model calculations. The talk also highlights new insights that challenge the assumption of universal parton-to-hadron fragmentation with an emphasis on heavy-flavour hadrons.
