论文摘要
我们介绍了一项现象学研究,该研究使用正向质子检测器,例如Atlas forward Proton或CMS-Totempotem Precision Procon Spectrometer检测器。最终的状态考虑了在大型拉迪乌斯喷气式喷气式飞机中至少在大型喷气式飞机中强化的$ W $玻色子衰减的最终状态。后者扩大了以前的努力,这些努力仅考虑了纯鳞状的最终状态。独家$ W^+W^ - $的测量还使我们能够进一步限制光子和$ W $玻色子之间异常的四分之一仪表的相互作用。与尺寸六的有效运算符相关的异常四分音量规耦合$ a_ {0,c}^w $的预期限制是针对HADRONIC,SEMI-LEPTONIC和LEPTONIC最终状态的。发现耦合可以探测到$ a_ {0}^w = 3.7 \ times 10^{ - 7} $ gev $^{ - 2} $和$ a_ {c}^w = 9.2 w = 9.2 \ times 10^{ - 7} $ gev $^at的$ cl^at an Lum cl^at an Lum cl^at an Lum cl^at 3 = 9.2 fb $^{ - 1} $通过组合所有最终状态,与$ a_ {0}^w = 4 \ times 10^{ - 6} $ gev $^{ - 2} $和$ a_ {c}^w = 1 \ times 10^{-5} $ gev $ geev $^nyy fordive fordies forece ferece ferece forde forde ferece ferection ferect ferection ferect ferect for的值
We present a phenomenology study on central exclusive production of $W^+W^-$ boson pairs in proton-proton collisions at the Large Hadron Collider at 14 TeV using the forward proton detectors, such as the ATLAS Forward Proton or the CMS-TOTEM Precision Proton Spectrometer detectors. Final states where at least one of the $W$ bosons decay hadronically in a large-radius jet are considered. The latter extends previous efforts that consider solely leptonic final states. A measurement of exclusive $W^+W^-$ also allows us to further constrain anomalous quartic gauge boson interactions between photons and $W$ bosons. Expected limits on anomalous quartic gauge couplings $a_{0,C}^W$ associated to dimension-six effective operators are derived for the hadronic, semi-leptonic, and leptonic final states. It is found that the couplings can be probed down to one-dimensional values of $a_{0}^W = 3.7\times 10^{-7}$ GeV$^{-2}$ and $a_{C}^W = 9.2 \times 10^{-7}$ GeV$^{-2}$ at $95\%$ CL at an integrated luminosity of 300 fb$^{-1}$ by combining all final states, compared to values of about $a_{0}^W = 4\times 10^{-6}$ GeV$^{-2}$ and $a_{C}^W = 1\times 10^{-5}$ GeV$^{-2}$ at 95\% CL expected for the leptonic channel alone.
