摘要:

利用费米实验室升级的对撞机探测器,在积分亮度为2.5 fb-1的条件下,测量了Z/γ^* 衰变为正负电子对的Z/γ^* 事例中包含喷流截面与喷流横向动量和喷流多重数的关系。测量覆盖了快度区|伊杰特|30 < 2.1 and the transverse momentum range ptjet >GeV/c。次领先阶微扰QCD预言与测量的截面符合得很好。

英文摘要:

Inclusive jet cross sections in Z/γ^* events, with Z/γ^* decaying into an electron-positron pair, are measured as a function of jet transverse momentum and jet multiplicity in ppbar collisions at sqrt{s} = 1.96 TeV with the upgraded Collider Detector at Fermilab in Run II, based on an integrated luminosity of 2.5 fb-1. The measurements cover the rapidity region |yjet | < 2.1 and the transverse momentum range ptjet > 30 GeV/c. Next-to-leading order perturbative QCD predictions are in good agreement with the measured cross sections.
