用ATLAS实验测量质心能量为$\sqrt{s}$ = 13 TeV的PDMATHAAB碰撞中的$W^+W^-$产生截面

Measurement of the $W^+W^-$ production cross section in $pp$ collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV with the ATLAS experiment

ATLAS Collaboration

摘要:

在$\sqrt{s}$ = 13 TeV的质子-质子碰撞中产生的相反电荷$W$ -玻色子对是使用2015年欧洲核子研究中心大型强子对撞机的ATLAS探测器收集的对应于积分亮度的3.16 fb $^{-1}$的数据测量的。候选的$W$ -玻色子对通过识别它们的轻子衰变为电子、μ子和中微子来选择。具有重建射流的事件不包括在候选事件样本中。在接近实验接受度的基准相空间中进行横截面测量,并与理论预测进行比较。测量结果与最精确的计算结果一致。

英文摘要:

The production of opposite-charge $W$-boson pairs in proton-proton collisions at $\sqrt{s}$ = 13 TeV is measured using data corresponding to 3.16 fb$^{-1}$ of integrated luminosity collected by the ATLAS detector at the CERN Large Hadron Collider in 2015. Candidate $W$-boson pairs are selected by identifying their leptonic decays into an electron, a muon and neutrinos. Events with reconstructed jets are not included in the candidate event sample. The cross-section measurement is performed in a fiducial phase space close to the experimental acceptance and is compared to theoretical predictions. Agreement is found between the measurement and the most accurate calculations available.
