We present a new measurement of the B(+) meson differential cross section d sigma/dp(T) at root 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/psi K(+), with J/psi ->mu(+)mu(-). The integrated cross section for producing B(+) mesons with p(T)>= 6 GeV/c and |y| <= 1 is measured to be 2.78 +/- 0.24 mu b.

Abstract
We present a new measurement of the B(+) meson differential cross section d sigma/dp(T) at root 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/psi K(+), with J/psi ->mu(+)mu(-). The integrated cross section for producing B(+) mesons with p(T)>= 6 GeV/c and |y| <= 1 is measured to be 2.78 +/- 0.24 mu b.File in questo prodotto:
