数据中$F_2$和$F_2^c$的几何标度以及QCD参数化

G. Beuf, C. Royon, D. Salek

摘要:

利用品质因数方法分析了质子DIS截面及其粲度分量在低$x$下的标度特性。标度性质进行了测试,无论是在深非弹性散射数据和结构函数重建CTEQ,MRST和GRV参数化的部分子密度函数。DIS截面的结果在数据和参数化之间是完全兼容的。即使有更大的误差条,魅力组件数据有利于相同的几何缩放属性的包容性DIS。这不是所有的魅力组件的参数化的情况。

英文摘要:

The scaling properties at low $x$ of the proton DIS cross section and its charm component are analyzed with the help of the quality factor method. Scaling properties are tested both in the deep inelastic scattering data and in the structure functions reconstructed from CTEQ, MRST and GRV parametrisations of parton density functions. The results for DIS cross sections are fully compatible between data and parametrisations. Even with larger error bars, the charm component data favors the same geometric scaling properties as the ones of inclusive DIS. This is not the case for all parametrisations of the charm component.
