Abstract

In the framework of k T -factorization QCD approach and the colour singlet model we consider J/ψ deep inelastic leptoproduction processes at HERA. We investigate the dependences of the single differential cross section on different forms of the unintegrated gluon distribution. The z and P T dependences of the spin aligment parameter α are presented also. Our theoretical predictions agree well with recent data taken by the H1 and ZEUS collaborations at HERA. It is shown that experimental study of the polarization J/ψ mesons at low Q 2 < 1 GeV2 is an additional test of BFKL gluon dynamics.
