The effects of CP-symmetry violation in the interaction of a photon and a Z-boson with t-quarks are studied. The interaction vertices of the photon and the Z-boson with t-quarks are found in a one-loop model with the Higgs boson exchange. The energy dependence of the asymmetries of b-quarks and antiquarks is calculated at energy up to 1.2 TeV. Simulation of parton processes, in which one pair of massive b-anti-b quarks together with 0, 1, and 2 gluons and massless quarks and two pairs of b-anti-b quarks are produced in proton-proton collisions, is carried out. The performed calculations account the first four orders of QCD perturbation theory in the one-loop approximation. The results of the calculations are compared with the data of ALICE and LHCb at energies 5, 8 and 13 TeV, obtained in 2013 - 2021.
