Measurement of the B meson differential cross-section in p{bar p} collisions at {radical}s = 1.8 TeV

PDF Version Also Available for Download.

Description

This paper presents a direct measurement of the differential {ital B}{sup +} and {ital B}{sup 0} cross sections, {ital d{sigma}/dp{sub T}} in {ital p}{ital {anti p}} collisions at {radical}s = 1.8 TeV using a sample of 74 {ital pb}{sup -1} accumulated by the Collider Detector at Fermilab (CDF). The cross sections are measured in the central pseudorapidity region {vert_bar}{eta}{vert_bar} {lt} 1 for {ital p{sub T}}({ital B}) {gt} 6.0 GeV/c by fully reconstructing the {ital B} meson decays {ital B}{sup +} {r_arrow} {ital J/{psi}K{sup +}} and {ital B}{sup 0} {r_arrow} {ital J/{psi}K{sup *0}}(892), where {ital J/{psi}} {r_arrow} {mu}{sup +}{mu}{sup -} and ... continued below

Description

This paper presents a direct measurement of the differential {ital B}{sup +} and {ital B}{sup 0} cross sections, {ital d{sigma}/dp{sub T}} in {ital p}{ital {anti p}} collisions at {radical}s = 1.8 TeV using a sample of 74 {ital pb}{sup -1} accumulated by the Collider Detector at Fermilab (CDF). The cross sections are measured in the central pseudorapidity region {vert_bar}{eta}{vert_bar} {lt} 1 for {ital p{sub T}}({ital B}) {gt} 6.0 GeV/c by fully reconstructing the {ital B} meson decays {ital B}{sup +} {r_arrow} {ital J/{psi}K{sup +}} and {ital B}{sup 0} {r_arrow} {ital J/{psi}K{sup *0}}(892), where {ital J/{psi}} {r_arrow} {mu}{sup +}{mu}{sup -} and {ital K}{sup *0} {r_arrow} {ital K}{sup +}{pi}{sup -}. The prediction of next-to- leading order QCD is consistent with the shape of the differential cross section but is low by a factor of 2.1{+-}0.2{+-}0.3. The integrated {ital B} meson cross section for {ital p{sub T}}({ital B}) {gt} 6.0 GeV/c is determined to be {sigma}({ital B}{sup -} = 3. 54{+-}0.22{+-}0.53 {mu}{ital b}.
