Description

We present a dedicated analysis of nuclear PDFs that focuses on open heavy-flavour production in pA collisions. Using a larger heavy quark data set than in the baseline fit, we quantify the resulting constraints on nuclear PDFs, with particular sensitivity to the gluon modification in the shadowing region. We rely on perturbative QCD in the SACOT general-mass-variable-flavour-number scheme to describe the data and compare it to the previously used data-driven Crystal-Ball approach. To make repeated NLO computations feasible, we accelerate the calculations with PineAPPL fast-interpolation grids, enabling direct SACOT predictions in the fit.
