Description
We investigate the cos2𝜙𝑡 azimuthal asymmetry in 𝑒 𝑝→𝑒 𝐽/𝜓 𝐽𝑒𝑡 𝑋, where 𝐽/𝜓-jet
pair is almost back-to-back in the transverse plane, within the framework of the
generalized parton model(GPM). We use non-relativistic QCD(NRQCD) to calculate
the 𝐽/𝜓 production amplitude and incorporate both color singlet(CS) and color
octet(CO) contributions to the asymmetry. We estimate the asymmetry using different
parametrizations of the gluon TMDs in the kinematics that can be accessed at the
future electron-ion collider (EIC) and also investigate the impact of transverse
momentum dependent (TMD) evolution on the asymmetry. We present the contributions
coming from different states to the asymmetry in NRQCD.
