Inclusive J/? photoproduction at the ILC within the framework of non-relativistic QCD

A bstract Based on the non-relativistic quantum chromodynamics factorization framework, we study inclusive J/? photoproduction at future high energy e + ? collider, International Linear Collider(ILC), where initial photons come from back-scattering of laser and electron (positron). The intermediate states, $$ c\overline{c} c ¯ ( 3 {S}_1^{\left[\mathbf{1}\right]} S 1 , 1 {S}_0^{\left[\mathbf{8}\right]} 0 8 {S}_1^{\left[\mathbf{8}\right]} {P}_{0,1,2}^{\left[\mathbf{8}\right]} P , 2 ), resolved processes are considered. Numerical results show that cross section ILC could be very large, single pro- cess via ) state dominates primarily production. We also present various kinematic distributions for photoproduction. Combining luminosity collision, shall provide a good platform to test NRQCD factorization.
