Received 10 December 2006; published 29 January 2007
We present a new measurement of the B+ meson differential cross section dσ/dpT at √s=1960 GeV. The data correspond to an integrated luminosity of 739 pb-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≥6 GeV/c and |y|≤1 is measured to be 2.78±0.24 μb.
