SUMMARY:Pheno Journal Club: 'Is the Strong CP Problem Really a Problem?'
DESCRIPTION:Speaker: Giulio Barni (IFT) \nVenue & Time: 14:30 – 15:30 \nAbstract: The vanishingly small value of the QCD θ-angle inferred from neutron EDM bounds is usually taken as evidence for the Strong CP Problem\, prompting a wide range of proposed solutions. In this talk\, I will first review what the Strong CP Problem is: why a generic θ term in QCD leads to large CP violation\, and how current experiments force θ ≲ 10e-10. I will then summarize the main solution strategies\, including the Peccei–Quinn axion\, parity- or CP-based models\, and other less conventional ideas. The second part of the talk will focus on a more conceptual question raised in recent years: does the Strong CP Problem actually exist\, or could θ be unphysical once confinement and the full structure of QCD are properly taken into account? Building on the recent analysis of Benabou\, Hook\, Manzari\, Murayama and Safdi (arXiv:2510.18951)\, I will discuss this debate\, highlighting what lattice QCD teaches us about θ-dependence\, topological sectors\, and the neutron EDM.
