Description

We discuss the implementation of general mass variable flavor number (GMVFN) schemes (such as ACOT or S-ACOT) for the treatment of heavy-quark mass effects in global PDF analyses at higher orders in QCD in terms of subtraction and residual PDFs. We present the application to Z+heavy flavor production and other cases of interest for precision phenomenology at hadron colliders.
