In this work the B-mesons differential cross sections in pp collisions are evaluated considering the color dipole formalism in transverse momentum representation along with the unintegrated gluon distributions (UGDs). Analytical parametrizations for UGDs including hard scale QCD evolution and those based on parton saturation framework are compared. The theoretical predictions for the B-meson production in terms of the transverse momentum distribution cover the center-of-mass energy of the Large Hadron Collider and the rapidities available at its experiments. The results for different B-mesons are compared to the corresponding measurements reported by the ATLAS, CMS, and LHCb experiments. Predictions are also performed for the nuclear modification factor as a function of the meson transverse momentum.
