Abstract: 

Xavi Ponce, de Padova University, will present the paper CP Conservation in the Presence of Pseudoparticles R. D. Peccei and Helen R. Quinn Phys. Rev. Lett. 38, 1440.

Abstract: We give an explanation of the CP conservation of strong interactions which includes the effects of pseudoparticles. We find it is a natural result for any theory where at least one flavor of fermion acquires its mass through a Yukawa coupling to a scalar field which has nonvanishing vacuum expectation value.
