Title: Higher-dimensional QCD without the strong CP problem
Authors: Izawa, K.-I.1,2 izawa@hep-th.phys.s.u-tokyo.ac.jp, Watari, T.1, Yanagida, T.1,2
Source: Physics Letters B. May2002, Vol. 534 Issue 1-4, p93. 4p.
Subjects: Quantum chromodynamics, Nuclear physics
Abstract: QCD in a five-dimensional sliced bulk with chiral extra-quarks on the boundaries is generically free from the strong CP problem. Accidental axial symmetry is naturally present except for suppressed breaking interactions, which plays a role of the Peccei–Quinn symmetry to make the strong CP phase sufficiently small.
