在Tevatron上测量W玻色子质量

W boson mass measurement at the Tevatron

I. Bizjak

摘要:

W玻色子的质量是电弱相互作用中测量得最不精确的参数之一。面对其他标准模型参数的测量,它可以检验标准模型的内部一致性,并可以约束标准模型希格斯玻色子的可能质量。CDF合作已经发布了目前使用200 pb-1的CDF Run II p-pbar数据对W玻色子质量的最精确测量,并且正在进行使用2.4 fb-1的CDF Run II数据的改进测量。这两种测量方法都在这些程序中详细描述。

英文摘要:

The mass of the W boson is one of the least precisely measured parameters of the electroweak interaction. Confronted with other measurements of standard model parameters it can test the internal consistency of the Standard Model and can constrain the possible mass of the standard model Higgs boson. The CDF collaboration has published the current single most precise measurement of the W boson mass using 200 pb-1 of CDF Run II p-pbar data, and an improved measurement with 2.4 fb-1 of CDF Run II data is underway. Both measurements are described in detail in these proceedings.
