在sqrt(s)= 1.96 TeV时测量伽马+ c + X和伽马+ b + X产生截面

Measurement of gamma + c + X and gamma + b + X production cross sections at sqrt(s) = 1.96 TeV

摘要:

光子加重味夸克(b,c)的末态提供了一个独特的和有价值的窗口,既可以看到质子的海夸克含量,也可以看到胶子分裂成重味夸克对。一种新的实验技术组合为首次测量sqrt(s)= 1.96 TeV的γ + c + X和γ + b + X微分产生截面提供了基础。测量使用D 0探测器收集的p-pbar碰撞的~1 fb-1数据。

英文摘要:

The photon plus heavy-flavour quark (b, c) final state provides a unique and valuable window into both the sea quark content of the proton and the splitting of gluons into heavy-flavour quark pairs. A new combination of experimental techniques has provided the basis for the first measurements of the differential gamma + c + X and gamma + b + X production cross sections at sqrt(s) = 1.96 TeV. The measurements use ~1 fb-1 of data from p-pbar collisions collected with the D0 detector.
