The B-s(0) differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at root s = 7 TeV, using the B-s(0) - GT J/psi phi decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, collected by the CMS experiment at the LHC, corresponds to an integrated luminosity of 40 pb(-1). The B-s(0) is reconstructed from the decays J/psi - GT mu+mu- and phi - GT K+K-. The integrated B-s(0) cross section times B-s(0) - GT J/psi phi branching fraction in the range 8 LT p(T)(B) LT 50 GeV/c and vertical bar y(B)vertical bar LT 2.4 is measured to be 6.9 +/- 0.6 +/- 0.6 nb, where the first uncertainty is statistical and the second is systematic.
