Here we have considered $J/\Psi$ is a normal charmonium meson, while $\Psi(2S)$ is a mixed hybrid charmonium meson. Similarly $\Upsilon(1S)$ and$\Upsilon(2S)$ are normal upsilon mesons, while $\Upsilon(3S)$ is a mixed hybrid upsilon meson.…
This is an extension of recent studies for $\Upsilon(nS), n=1,2,3,$ and $J/\Psi(1S),\Psi(2S)$ production at the LHC in pp collisions, and with the ALICE detector at 7.0 TeV, with new predictions at 8.0 TeV
