Quark masses and the strong CP problem
Presented by Michael Creutz, Cofounder of lattice gauge theory, Brookhaven National Lab
I discuss why, contrary to common lore, the possibility of having a massless up quark is unrelated to the strong CP problem. A closely related issue is an ambiguity in defining topological susceptibility in QCD.
