The quest for new sources of the simultaneous violation $C$ and $CP$ symmetry was popular in 1960s has since been mostly neglected more than half a century. In this work we revisit fundamental quark-level operators that break up to including mass dimension 8 flavor-conserving transitions, relying on complete operator sets so-called Standard Model effective field theory low-energy theory. With formalism chiral perturbation theory, match these quark light-meson physics, derive $C$- $CP$-odd...
A bstract Based on recent progress in the systematic analysis of C and CP violation light-meson sector, we calculate -odd transition amplitudes η → π 0 ℓ + − ′ ηℓ . Focusing long-distance contributions driven by lowest-lying hadronic intermediate states, work out correlations between these beyond-the-Standard-Model signals Dalitz-plot asymmetries ηπ , using dispersion theory.
Based on recent progress in the systematic analysis of $C$ and $CP$ violation light-meson sector, we calculate $C$-odd transition amplitudes $\eta\to\pi^0\ell^+\ell^-$ $\eta'\to\eta\ell^+\ell^-$. Focusing long-distance contributions driven by lowest-lying hadronic intermediate states, work out correlations between these beyond-the-Standard-Model signals Dalitz-plot asymmetries $\eta \rightarrow \pi^0 \pi^+ \pi^-$ $\eta' \eta \pi^- $, using dispersion theory.
