$J/\Psi$ and ${\chi }_{cJ}(J=0,1)$ production in electron-positron annihilation at $\sqrt{s}=10.6$ GeV in the framework of Bethe-Salpeter equation

Shashank Bhatnagar, Teresa Aruja, Vaishali Guleria

In present work we study the production of ground and excited charmonium pairs in $e^{-}{e}^{+}\to \Psi (nS)+{\chi }_{cJ}(nP)$ for $J=0,1$ and $n=1,2$, through leading order (LO) tree-l…
