Beauty production cross section per rapidity unit at midrapidity as a function of $\s$ as measured in pp collisions by the ALICE and PHENIX Collaborations and in $\ppbar$ collisions by the CDF and UA1 Collaborations. The ALICE data points are shifted in the $\s$-axis for better visibility. The solid and dashed lines with the shaded band represents the FONLL and NNLO calculations with their uncertainties, respectively.
