We calculate the TMD sea quark density as a convolution of the Catani-Ciafaloni-Fiorani-Marchesini (CCFM)-evolved gluon distribution and the TMD gluon-to-quark splitting function. Based on the ${\\cal O}(\\alpha^2)$ production amplitude $q^* + \\bar q^* \\to Z/\\gamma^* \\to l^+ + l^-$, calculated by taking into account the effective $q^*\\bar q^* Z/\\gamma^*$ - vertex, we analyze the distributions on the dilepton invariant mass, ","authors_text":"A.V.
