LHC上W产生电荷不对称性的直接测量

On direct measurement of the W production charge asymmetry at the LHC

K. Lohwasser, J. Ferrando, C. Issever

摘要:

提出了在LHC的W生产电荷不对称性的直接测量的前景进行了讨论。在Tevatron所使用的方法的修改建议在LHC的测量。预期的灵敏度,这样的测量部分子分布函数的轻子电荷不对称性的测量相比。直接测量的方法被发现是不太有用的放置在LHC的部分子分布函数的约束比轻子电荷不对称性的测量。

英文摘要:

The prospects for making a direct measurement of the W production charge asymmetry at the LHC are discussed. A modification to the method used at the Tevatron is proposed for measurements at the LHC. The expected sensitivity for such a measurement to parton distribution functions is compared to that for a measurement of the lepton charge asymmetry. The direct measurement approach is found to be less useful for placing constraints on parton distribution functions at the LHC than a measurement of the lepton charge asymmetry.
