Abstract

Modulo some highly plausible assumptions, we show that vector-like global symmetries (like isospin or baryon number) are not spontaneously broken in vector-like gauge theories with θ = 0 (like QCD). We also show that in these theories massless bound states do not form from massive constituents.
