The cross section of $$e^+e^-\rightarrow \Lambda \overline{\Sigma }{}^0+\text {c.c.}$$ e + e - → Λ Σ ¯ 0 + c.c. as a litmus test of isospin violation in the decays of vector charmonia into $$\Lambda \overline{\Sigma }{}^0+\text {c.c.}$$ Λ Σ ¯ 0 + c.c.
Abstract Under the aegis of isospin conservation, the amplitudes in Born approximation, i.e., considering the only one-photon-exchange mechanism, of the decay $$\psi \rightarrow \Lambda \overline{\Sigma }{}^0+\text {c.c.}$$ ψ → Λ Σ ¯ 0 + c.c. , where $$\psi $$ ψ is a vector charmonium, and of the re...
