CTEQ Spring meeting 2025

America/Detroit
Huey-Wen Lin, Paul Reimer, Reinhard Schwienhorst (Michigan State University (US))
Description

2025 Spring CTEQ meeting April 22-24, Zoom. The meeting consists of a one-day discussion focused on the PQCD/nPQCD transition regions in support of DUNE, then a one-day session that is open to everyone, and the last day is reserved for the CTEQ-internal business meeting.

Please register so that we can an idea of the expected zoom attendance. Registration is free. Please let the organizers know if you would like to give a talk.

Organized by:
Huey-Wen Lin (MSU)
Paul Reimer (Argonne)
Jorge Morfin (FNAL, Day 1)
Reinhard Schwienhorst (MSU, indico)

      Subtraction and Residual PDFs: Heavy-quark treatments in global QCD analyses 20m

      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.
