We present a new measurement of the B+ meson differential cross section dσ/dpT at s=1960GeV. The data correspond to an integrated luminosity of 739pb-1 collected with the upgraded CDF detector (CDF II) at the Fermilab Tevatron collider. B+ candidates are reconstructed through the decay B+→J/ψK+, with J/ψ→μ+μ-. The integrated cross section for producing B+ mesons with pT≥6GeV/c and |y|≤1 is measured to be 2.78±0.24μb. © 2007 The American Physical Society.
