H. Jung, M. Kraemer, A. V. Lipatov, N. P. Zotov

摘要:

我们提出强子级预测的Monte Carlo发生器级联和部分子级计算的开b夸克,b味强子和包容的b喷流的产生的框架下的kt-因子化QCD方法的LHC能量。利用CCFM演化方程和Kimber-Martin-Ryskin(KMR)公式计算了质子中未积分的胶子密度。我们的预测进行了比较,在7 TeV的CMS和LHCb合作采取的第一个数据。我们研究的理论不确定性,我们的计算和调查的影响来自部分子淋浴在初始和最终状态。指出了初胶子横动量在描述数据中的特殊作用。

英文摘要:

We present hadron-level predictions from the Monte Carlo generator Cascade and parton level calculations of open b quark, b-flavored hadron and inclusive b-jet production in the framework of the kt-factorization QCD approach for the LHC energies. The unintegrated gluon densities in a proton are determined using the CCFM evolution equation and the Kimber-Martin-Ryskin (KMR) prescription. Our predictions are compared with the first data taken by the CMS and LHCb collaborations at 7 TeV. We study the theoretical uncertainties of our calculations and investigate the effects coming from parton showers in initial and final states. The special role of initial gluon transverse momenta in description of the data is pointed out.
