Near-threshold structures in seven e+e- annihilation channels are simultaneously described by a single chiral-EFT N Nbar final-state interaction plus slowly varying short-distance sources, without channel-specific narrow resonances.
Equivalently, the particle-basis transition parameters satisfyv h(L,p) =v h(L,n) for the isospin-0 channels and vh(L,p) =−v h(L,n) for the isospin-1 channels

Understanding the near-threshold structures in $e^+e^- $ annihilation from a unified $N \bar N$-interaction perspective
Near-threshold structures in seven e+e- annihilation channels are simultaneously described by a single chiral-EFT N Nbar final-state interaction plus slowly varying short-distance sources, without channel-specific narrow resonances.
