Tevatron Jet、W/Z +Jet和重口味生产成果综述

Review of Recent Tevatron Jet, W/Z+Jet and Heavy-flavor Production Results

Shin-Shan Yu

摘要:

本文回顾了费米实验室兆电子伏特加速器最近的几次测量,包括包容性喷流、双喷流产生的截面、与包容性或重味(b或c)喷流相关的电弱玻色子(W或Z)产生的截面以及b喷流形状。此外,搜索新的物理使用dijet角分布进行了讨论。这些分析是基于用CDF和D_0探测器收集的\sqrt{s} =1.96 TeV的p-pbar碰撞的0.3- 2.5/fb的积分亮度。结果直接测试了微扰量子色动力学的首阶和次首阶计算,并提供了对部分子分布函数、胶子分裂贡献和超越标准模型的物理的约束。

英文摘要:

This document reviews several recent measurements at the Fermilab Tevatron, including the cross sections of inclusive jet, dijet production, the cross sections of electroweak boson (W or Z) production in association with inclusive or heavy-flavor (b or c) jets, and b-jet shapes. In addition, searches for new physics using the dijet angular distributions are discussed. These analyses are based on integrated luminosities of 0.3--2.5/fb of p-pbar collisions at \sqrt{s}=1.96 TeV, collected with the CDF and D0 detectors. The results directly test the leading order and next-to leading order calculations of perturbative quantum chromodynamics and provide constraints on the parton distribution functions, gluon-splitting contribution, and physics beyond the standard model.
