QCD Wilson lines in IR chiral Lagrangian
By Ho Tat Lam
Appears in collection : Symmetry and Topology in Partical Physics
In this talk, we will answer the question: What does a QCD Wilson line flow to in the IR chiral Lagrangian? We will first present a symmetry-based argument showing that the Wilson line is not completely screened in the IR. We then propose a disorder operator realization of the Wilson line in the chiral Lagrangian. This allows us to model heavy-light mesons and baryons and describe the dissolution of confining strings into pions within the chiral Lagrangian.
