Measurement of the B meson differential cross-sections in p{anti p} collisions at {radical}s = 1.8 TeV using the exclusive decays B{sup {+-}} {yields} J/{psi}K{sup {+-}} and B{sup 0} {yields} J/{psi}K*{sup 0}
This paper presents the first measurement of the differential B{sup {+-}} and B{sup 0} cross-sections, d{sigma}/dp{sub {Tau}}, in p{anti p} collisions at {radical}s = 1.8 TeV. The data sample used represents an integrated luminosity of 19.3 {+-} 0.8 pb{sup {minus}1} accumulated by the Collider Detector at Fermilab (CDF). The cross-sections are measured over the p{sub T} range 6--15 GeV/c in the central pseudorapidity region {vert_bar}{eta}{vert_bar} < 1 by fully reconstructing the B meson decays B{sup {+-}} {yields} J/{psi}K{sup {+-}} and B{sup 0} {yields} J/{psi}K*{sup 0}, where the J/{psi} is required to decay to two muons, and the K*{sup 0} is required to decay to K{sup {+-}}{pi}{sup {-+}}. The measured absolute normalization and shape of the cross-section as a function of p{sub {Tau}} are compared to the theoretical QCD prediction calculated at next-to-leading order.
