在Tevatron上的W玻色子运动学分析:ResBos重建和Pythia generator的比较

W Boson Kinematic Analysis at the Tevatron: A comparison of ResBos resummation and Pythia generator

Moh'd A. Hussein

摘要:

本文用ResBos程序和Monte Carlo事件发生器Pythia给出了Tevatron(ppbar -> W X -> e \u{psion}_e X)中包含W玻色子产生的微分截面分布的运动学特征,并发现它们之间的关系是基本一致的。虽然这两个程序都再现了W玻色子的基本定性特征,但分布验证了就W玻色子的不变质量和其他电弱精确测量而言,Pythia不能用作ResBos的可靠替代品。

英文摘要:

The kinematical features of the differential cross section distributions in inclusive W boson production at the Tevatron (ppbar -> W X -> e \u{psion}_e X) are presented using the resummation program ResBos, and the Monte Carlo event generator Pythia, and are found to be in marginal agreement with each other. While both programs reproduce the basic qualitative features of W boson, the distributions validate that Pythia can't be used as a reliable substitute for ResBos as far as the invariant mass of W boson and other electroweak precision measurements are concerned.
