Accessing unpolarized and linearly polarized gluon TMDs through quarkonium production

Abstract: We present the study of accessing unpolarized and linearly polarized gluon TMDs in J/{\psi} and {\Upsilon}(1S) production in unpolarized proton-proton collision at LHC, RHIC and AFTER energies. Non- relativistic QCD based color octet model (COM) is used for estimating quarkonium production rates within transverse momentum dependent factorization formalism. A comparison is drawn between the experimental data and the transverse momentum distribution of quarkonium obtained in COM and color evaporation model.
