在LHC上直接产生光子和重夸克喷流

Direct Photon and Heavy Quark Jet Production at the LHC

T. Stavreva

摘要:

在LHC的直接光子和重夸克的相关生产。在ALICE的截面的核修改因子的预测。结果表明,这一过程是对胶子和重夸克核PDF的一个很好的探索,因为它在NLO处的nPDF依赖性的80%以上来自这些nPDF。因此,对这个过程的测量将为胶子nPDF提供一个很好的约束,并将区分目前市场上不同的nPDF集。

英文摘要:

The associated production of direct photons and heavy quarks at the LHC is presented. Predictions for the nuclear modification factor to the cross-section at ALICE are shown. It is demonstrated that this process is a great probe of the gluon and heavy quark nuclear PDFs, as over 80 % of its nPDF dependence at NLO comes from those nPDFs. Therefore measurements of this process will provide an excellent constraint on the gluon nPDF, and will distinguish between different nPDF sets currently out on the market.
