We study non-prompt J/ψ+μ and J/ψ+J/ψ production at LHC within kT-factorization. We present description of ATLAS and LHCb collaboration data. The processes are found to be sensitive to the choice of the transverse momentum dependent (TMD, unintegrated) parton distribution functions. KMR appears to give better description of the data. Effects of double parton scattering and parton showers are found to be negligible.
