标题： Recombination Methods for Jets in $p\pbar$ Collisions

摘要： 一种喷注算法必须说明如何（重新）组合不同的部分子或塔 into 一个四维矢量。 各种重新组合方案已被实验上用于研究强子对撞机中喷注的横向能量分布。 通常情况下，数据对所使用的方案不敏感。 然而，我们认为之前\DO 合作组使用的重新组合方案预期会有较大的微扰修正，因此不应用于与固定阶微扰理论进行定量比较的目的。 显示英文摘要

摘要： A jet algorithm must specify how to (re-)combine different partons or towers into a single four-vector. Various recombination schemes have been used experimentally to examine the transverse energy profile of jets in hadron colliders. Generally, the data is insensitive to which scheme is used. However, we argue that the recombination scheme previously used by the \DO\ collaboration is expected to have large perturbative corrections and should not be used for the purposes of making a quantitative comparison with fixed-order perturbation theory.
