Fraction of \PJpsi from the decay of b-hadrons at mid-rapidity as a function of the \pt\ of \PJpsi in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV compared with results from ATLAS  in the same colliding system and results of ALICE , ATLAS  and CMS  in pp collisions at either $\sqrt{s}=7$ TeV or $\sqrt{s}=8$ TeV Results from CDF  in ${\rm p \overline{p}}$ collisions at $\sqrt{s}=1.96$ TeV are also shown The ALICE data symbols are placed horizontally at the average value of the \pt\ distribution of each interval (see text for details) For all experiments, the vertical error bars represent the quadratic sum of the statistical and systematic errors In the interval $1.3 < \Pt < 3 $ GeV/$c$ the upper limit at the 95\% confidence level is shown, as discussed in the text
