Quark masses and the strong CP problem

Thursday April 6, 2017
4:00 pm

 Presenter:  Michael Creutz, Cofounder of lattice gauge theory, Brookhaven National Lab
 Series:  Nuclear, Particle, Astroparticle and Cosmology (NUPAC) Seminars
 Abstract:  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.
