We present the main results of our recent analyses of exclusive production of vector charmonia (J/ψ and ψ′) in kt-factorization approach and for γγ production of charged dilepton pairs in exclusive and semiinclusive processes in a new approach, similar in spirit to kt-factorization.
The results for charmonia are compared with recent results of the LHCb collaboration. We include some helicity flip contributions and quantify the effect of absorption correction. The effect of cc̅ wave function is illustrated.
We present uncertainties related to F2 structure function which are the main ingredient of the approach. Our results are compared with recent CMS data for dilepton production with lepton isolation cuts imposed.
