论文摘要
使用完整的前向质子来对质子 - 普罗顿碰撞的独家高质量$γγ$ $ \ to $ ww进行搜索，并使用完整的前向质子进行了近光探测器的完整质子，而较弱的玻色子都腐烂成增压和合并的jets。该分析基于CMS和TOTEM实验收集的质子 - 质子碰撞样本，以$ \ sqrt {s} $ = 13 TEV，对应于100 fb $^{ - 1} $的集成光度。没有观察到超过标准模型背景预测的过量，并且在PP $ \ \ $ pwwp和Pp $ \ to $ pzzp跨部门上设置了上限，该基金会由Diboson不变性质量$ $ M $ $ $（vv）$ \ lt $ 1 tev（v = w，z）和proton $ $ $ $ $ $ $ 04 $ 04 $ $ $ $ $ 04 $ 04 0.20。结果被解释为尺寸6和尺寸8异常的四分之一量规耦合的新限制。
A search is performed for exclusive high-mass $γγ$ $\to$ WW and $γγ$ $\to$ ZZ production in proton-proton collisions using intact forward protons reconstructed in near-beam detectors, with both weak bosons decaying into boosted and merged jets. The analysis is based on a sample of proton-proton collisions collected by the CMS and TOTEM experiments at $\sqrt{s}$ = 13 TeV, corresponding to an integrated luminosity of 100 fb$^{-1}$. No excess above the standard model background prediction is observed, and upper limits are set on the pp $\to$ pWWp and pp $\to$ pZZp cross sections in a fiducial region defined by the diboson invariant mass $m$(VV) $\lt$ 1 TeV (with V = W, Z) and proton fractional momentum loss 0.04 $\lt$ $ξ$ $\lt$ 0.20. The results are interpreted as new limits on dimension-6 and dimension-8 anomalous quartic gauge couplings.
