标题： Evidence for breakdown of the DGLAP description in diffractive DIS at HERA

摘要： HERA关于衍射深度非弹性散射的数据在$Q^2\sim 5$ GeV$^2$低质子 $\xi$时显示出与扭2 DGLAP预测的偏差，这可能高达100%。 这些偏差与从饱和模型中提取的高扭效应一致。 这是对深度非弹性散射中高扭效应的首次直接证据。 这一发现影响了用于LHC预测的衍射部分子密度的确定。 显示英文摘要

摘要： HERA data on diffractive DIS show deviations from twist 2 DGLAP predictions below $Q^2\sim 5$ GeV$^2$ at low pomeron $\xi$, which may reach up to 100%. These deviations are consistent with higher twists effects extracted from the saturation model. It is a first direct evidence for the higher twists in DIS. This finding affects determination of the diffractive parton densities that are used for the predictions at the LHC.
