The recent measurement by the UA1 group of the cross section for bottom-quark production with transverse momentum greater than 5 GeV is found to be in good agreement with the simplest, lowest-order computations in perturbative quantum chromodynamics. This may be contrasted with the well-known disagreement for the much lighter charm quark. Further checks are discussed.
