In these proceedings preliminary measurements of the charged-particle b-jet production in p–Pb pp collisions at root sNN = 5.02 TeV performed with the ALICE experiment are reported. The presented analysis utilizes secondary vertex of b-hadron decays to identify b-jet candidates. The resulting fully corrected b-jet spectrum obtained in p–Pb collisions is compatible with the result of a simulation based on POWHEG HVQ and PYTHIA event generators. The nuclear modification factor of charged-particle b jets is found to be consistent with unity within uncertainties, suggesting that the production of b jets in p–Pb collisions at root sNN = 5.02 TeV is not affected by large cold nuclear-matter effects.
