标题： Universal parametrization of jet production based on parton and fragment rapidities

摘要： 作为高能核碰撞中QCD的标志性表现，喷注生成为该理论提供了关键的检验。 但事件级喷注重建可能很复杂且容易受到测量偏差的影响。 此外，以基本碰撞蒙特卡罗模型形式呈现的QCD理论也可能很复杂且难以测试。 构建一个简单的静态喷注生成模型在质子-质子碰撞中可能有益，以便于数据比较和模型测试。 QCD是一种对数理论，其特性随能量尺度的变化形式为$\log(s/s_0)$。 如在对数快速度上绘制的喷注相关数据，如部分子碎裂函数，表现出自相似的标度行为，仅用少数参数即可进行简单而准确的参数化。 在本研究中，我们将该方法扩展为基于某些测量的对数喷注生成趋势，构建喷注（散射部分子）动量谱的参数化。 该参数化使用 Spp̄S 喷注数据建立，然后外推以与Tevatron和LHC喷注数据进行比较。 此外，本研究中的喷注生成模型与质子-反质子碎裂函数的参数化相结合，用于预测最小偏倚喷注碎片对强子$p_t$谱的贡献。 该预测与已发表的质子-质子谱数据进行比较，以测试模型的自洽性。 显示英文摘要

摘要： As the signature manifestation of QCD in high energy nuclear collisions jet production provides essential tests of that theory. But event-wise jet reconstruction can be complex and susceptible to measurement bias. And QCD theory in the form of Monte Carlo models of elementary collisions can also be complex and difficult to test. It may be beneficial to construct a simple static model of jet production in p-p collisions to facilitate data comparisons and model tests. QCD is a logarithmic theory featuring variations with energy scale of the form $\log(s/s_0)$. Jet-related data such as parton fragmentation functions plotted on logarithmic rapidities exhibit self-similar scaling behavior which admits simple and accurate parametrization with only a few parameters. In this study we extend that method to construct a parametrization of jet (scattered parton) momentum spectra based on certain measured logarithmic jet production trends. The parametrization is established with Sp\=pS jet data and then extrapolated for comparison with Tevatron and LHC jet data. In addition, the jet production model from the present study is combined with a parametrization of p-\=p fragmentation functions to predict the minimum-bias jet fragment contribution to hadron $p_t$ spectra. The prediction is compared with published p-p spectrum data to test the self-consistency of the model.
