LHC中电弱玻色子横动量分布的非微扰效应

Non-perturbative effects in the transverse momentum distribution of electroweak bosons at the LHC

Andrzej Siodmok, Stefan Gieseke, Michael H. Seymour

摘要:

Drell-Yan过程中电弱玻色子的横动量是LHC实验计划中的一个重要量。本文提出的初态部分子簇射中的非微扰胶子发射的新模型,对以前实验中在宽的CM能量范围内所取得的数据,很好地描述了这个量。给出了该模型对LHC中Z玻色子横向动量分布的预测,并与其它方法进行了比较。

英文摘要:

The transverse momentum of electroweak bosons in a Drell-Yan process is an important quantity for the experimental program at the LHC. The new model of non-perturbative gluon emission in an initial state parton shower presented in this note gives a good description of this quantity for the data taken in previous experiments over a wide range of CM energy. The model's prediction for the transverse momentum distribution of Z bosons for the LHC is presented and used for a comparison with other approaches.
