TeV =1.96时ppbar碰撞中光子+b+X和光子+c+X产生截面的测量

Measurement of photon+b+X and photon+c+X production cross sections in ppbar collisions at sqrt(s)=1.96 TeV

D0 Collaboration, V. M. Abazov

摘要:

本文首次测量了与重夸克(c,b)喷注相关联的光子包容产生的微分截面,测量范围包括光子横动量30-150 GeV,光子快度|y γ| < 1.0,喷流速度|y_jet| < 0.8,喷流横向动量pT_jet > 15 GeV。这些结果是基于费米实验室Tevatron对撞机的D 0探测器在sqrt(s)=1.96 TeV的ppbar碰撞中记录的1 fb^-1的积分亮度得出的。结果进行了比较次领先阶微扰QCD预测。

英文摘要:

First measurements of the differential cross sections for the inclusive production of a photon in association with a heavy quark (c, b) jet are presented, covering photon transverse momenta 30-150 GeV, photon rapidities | y_gamma| < 1.0, jet rapidities |y_jet| < 0.8, and jet transverse momenta pT_jet > 15 GeV. The results are based on an integrated luminosity of 1 fb^-1 in ppbar collisions at sqrt(s)=1.96 TeV recorded with the D0 detector at the Fermilab Tevatron Collider. The results are compared with next-to-leading order perturbative QCD predictions.
