摘要:

我们总结了最近的发展的道路上的“MMHT 19”部分子分布函数。我们专注于提取的奇夸克后,改进的理论计算NNLO带电电流截面;的影响,我们的参数化的扩展;和相关的不确定性的作用,在一些数据集证明难以拟合。

英文摘要:

We summarise recent developments in the path towards the "MMHT19" parton distribution functions. We concentrate on the extraction of the strange quark upon the improvement of theoretical calculations for NNLO charged current cross sections; the effect of an extension of our parameterisation; and the role of correlated uncertainties in some data sets which prove difficult to fit.
