Isospin violating decays of vector charmonia
Abstract We study the isospin violating decays of vector charmonia to $$\Lambda \overline{\Sigma }^0$$ Λ Σ ¯ 0 and its charge conjugate. They are dominated by the single photon annihilation and can be evaluated reliably with timelike form factors. We utilize the quark-pair creation model, which is v...
