$\gamma ,J/\psi$ production through ISR process in electron-positron annihilation at B-factories

Shashank Bhatnagar

We study the Initial state radiation (ISR) process, $e^{-}{e}^{+}{\to }^{\ast }\gamma \to \gamma +J/\psi$ observed at high luminosity $e^{-}{e}^{+}$ colliders such as B-factories, with the ISR phot…
