Exclusive production of P-wave charmonia through two virtual photons in electron-positron annihilation
Avinash Okram, Shashank Bhatnagar
We present a relativistic study of the exclusive double-charmonium processes $e^-e^+ \to γ^*γ^* \to Ï_{c1}+η_c$ and $e^-e^+ \to γ^*γ^* \to h_c+h_c$ at GeV in…

production through ISR process in electron-positron annihilation at B-factories
Shashank Bhatnagar
We study the Initial state radiation (ISR) process, observed at high luminosity colliders such as B-factories, with the ISR p…
