Phenomenological interpolation of the inclusive J/psi cross section to proton-proton collisions at 2.76 TeV and 5.5 TeV

Understand

We present a study of the inclusive J/psi cross section at 2.76 TeV and 5.5 TeV.

• The energy dependence of the cross section, rapidity and transverse momentum distributions are evaluated phenomenologically.
• Their knowledge is crucial as a reference for the interpretation of A-A and p-A J/psi results at the LHC.
• Our approach is the following: first, we estimate the energy evolution of the pt-integrated J/psi cross section at mid-rapidity; then, we evaluate the rapidity dependence; finally, we study the transverse momentum distribution trend.
