高Q^2下DIS中包含射流的产生及强耦合的提取

Inclusive Jet Production in DIS at High Q^2 and Extraction of the Strong Coupling

Thomas Kluge

摘要:

利用HERA的H1探测器研究了大四动量转移平方Q^2>150 GeV^2时中性流正电子-质子深度非弹性散射中包含喷流的产生。在微扰QCD中,我们发现测量结果与次领先阶的计算结果吻合得很好。论证了强耦合的发生,并确定了α_s(M_Z)值。

英文摘要:

Inclusive jet production is studied in neutral current deep-inelastic positron-proton scattering at large four momentum transfer squared Q^2>150 GeV^2 with the H1 detector at HERA. The measurements are found to be well described by calculations at next-to-leading order in perturbative QCD. The running of the strong coupling is demonstrated and the value of alpha_s(M_Z) is determined.
