< p>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.< /p>
