Oliver Witzel, Siegan, [HET Seminar] Lattice QCD and Gradient Flow

Thursday 19 Mar 2026, 11:00 → 13:00 US/Eastern

Small Seminar Room

Lattice Quantum Chromodynamics (QCD) is a framework to perform ab initio 
calculations of the strong interactions with systematically improvable 
uncertainties. Precisely determining the lattice scale is one of the 
crucial steps. Introducing gradient flow scales provided tremendous 
improvements and are part of state-of-the-art scale determinations 
today. Gradient flow is, however, much more powerful and can also be 
used e.g. as an alternative renormalization scheme. I will demonstrate 
calculating renormalized quark masses using gradient flow. Eventually 
gradient flow has even more to offer and I will highlight determining 
bag parameters describing heavy meson lifetimes and give an outlook on 
possible different applications also including analytic calculations in 
the continuum.
