Modeling the production of B mesons in pp collisions at LHC energies

The spectra of the transverse momentum for B mesons of various types in pp interactions at center-of-mass energies 7 and 13 TeV were simulated with PYTHIA 8 event generator. Spectrum ratios for B mesons of different nature and the energy dependence of these distributions in the interval 7-13 TeV were obtained. It is shown that the spectra become more hard with increase of the proton collision energy.
