    abstract = "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) -> 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 -> mu+mu- and phi -> K+K-. The
integrated B-s(0) cross section times B-s(0) -> J/psi phi branching
fraction in the range 8 < p(T)(B) < 50 GeV/c and vertical bar
y(B)vertical bar < 2.4 is measured to be 6.9 +/- 0.6 +/- 0.6 nb, where
the first uncertainty is statistical and the second is systematic."
