Erzeugung schwerer Hadronen mit vorhandenen und zukünftigen Beschleunigern in einem massiven Schema mit veränderlicher Flavour-Zahl

几年来，在HERA、LEP2和Tevatron上测量的B介子产生率一直出名地超过通常对大质量b夸克(B强子反常)的下一级(NLO)QCD预测，高达三个标准差。这甚至引发了理论上的尝试，试图将这种偏差解释为超越标准模型的新物理信号。然而，这种偏差是否可以通过改进和完善QCD预测本身来解释，还有待澄清。为此，我们计划为在高能碰撞中包含产生重口味强子(H=D，B)阐述一个严格的理论形式主义。然后，我们将在该方案中评估NLO相关生产工艺的横截面，并对可用的D和B数据集进行全局分析，试图改善总体协议。利用所提取的FF，我们将为LHC和未来的e+e-线性对撞机提供可靠的预测。

For several years, the B-meson production rates measured at HERA, LEP2 and Tevatron have been notoriously exceeding, by up to three standard deviations, the usual next-toleading- order (NLO) QCD predictions for massive b quarks (B-hadron anomaly). This has even triggered theoretical attempts to interpret this deviation as a signal of new physics beyond the standard model. However, it remains to be clarified if this deviation can be explained by improving and refining the QCD prediction itself. To this end, we plan to elaborate a rigorous theoretical formalism for the inclusive production of heavy-flavoured hadrons (H = D, B) in high-energy collisions. ¿ We shall then evaluate the cross sections for the relevant production processes at NLO in this scheme and perform global analyses of the available D and B data sets trying to improve the overall agreement. Using the FFs thus extracted, we shall provide reliable predictions for LHC and a future e+ e- linear collider.
