标题： Vector boson scattering at the LHC. A study of the WW -> WW channels with the Warsaw cut

摘要： 我们研究在对撞机过程中不存在共振的情况下，同号和异号通道中的W玻色子散射。$pp\rightarrow l^{\pm}\nu_{l}l^{\pm}\nu_{l}jj$和$pp\rightarrow l^{\pm}\nu_{l}l^{\mp}\nu_{l}jj$分别代表这两种情况。基本的选择性切割以及对最终轻子和喷注动量组合的限制（即华沙切割）使得可以论证，在大型强子对撞机上，亮度为100 fb$^{-1}$且质心系能量为$\sqrt{s}= 13$TeV 将允许在千分之一水平上约束主要的有效拉格朗日系数。我们还讨论了有效拉格朗日其他系数的限制，以及更高能量和亮度提供的更强约束。我们表明，同号$WW \rightarrow WW$通道足以提供最严格的约束。 显示英文摘要

摘要： We study W boson scattering in the same- and opposite-sign channels under the assumption that no resonances are present in the collider processes $pp\rightarrow l^{\pm}\nu_{l}l^{\pm}\nu_{l}jj$ and $pp\rightarrow l^{\pm}\nu_{l}l^{\mp}\nu_{l}jj$, respectively. Basic selection cuts together with a restriction on the combination of the final lepton and jet momenta (the Warsaw cut) makes it possible to argue that at the LHC a luminosity of 100 fb$^{-1}$ and a center-of-mass energy of $\sqrt{s}= 13$ TeV will allow to constrain the leading effective lagrangian coefficients at the permil level. We also discuss limits on the other coefficients of the effective lagrangian as well as stronger constraints provided by higher energy and luminosity. We show that the same-sign $WW \rightarrow WW$ channel suffices in providing the most stringent constraints.
