Description
I review the recent efforts in the NNPDF collaboration towards a new extraction of polarized parton distributions functions (pPDF) which will be highly relevant for the upcoming Electron-Ion-Collider (EIC) experiments. This includes a recent study on heavy quark effects in polarized DIS, where we apply the FONLL prescription for the first time in a polarized setup and demonstrate the non-negligible impact specifically on the polarized gluon distribution. We show some preliminary results of the new pPDF release NNPDFpol2.0 based on the latest machine learning framework (as established in NNPDF4.0) and the new theory prediction pipeline. Finally, we report on a community effort to fully establish the evolution of pPDFs at NNLO accuracy.
