A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon–nucleon centre-of-mass energy 
TeV is presented. The semi-inclusive decay channel of beauty hadrons into is considered, where the mesons are reconstructed in the dielectron decay channel at mid-rapidity down to transverse momenta of 1.3 GeV/c. The 
production cross section at mid-rapidity, 
, and the total cross section extrapolated over full phase space, 
, are obtained. This measurement is combined with results on inclusive production to determine the prompt cross sections. The results in p–Pb collisions are then scaled to expectations from pp collisions at the same centre-of-mass energy to derive the nuclear modification factor 
, and compared to models to study possible nuclear modifications of the production induced by cold nuclear matter effects. is found to be smaller than unity at low 
for both coming from beauty hadron decays and prompt .
