论文摘要
在粒子物理学中对发现的追求始终需要以最高的能量进行研究。具有重要优势的多THEV MUON山着壁层为研究标准模型以外的新物理学提供了前所未有的潜力。我们广泛地假设一系列质量中心的能量从3到30 TEV，对于未来的多TEV MUON COLLIDERS而言，一系列的集成发光度从1到90 ab $^{ - 1} $。我们通过该过程对异常$WWγ$耦合进行现象学研究山脉。将$δ_{sys} = 0 $，$ 3 $，$ 5 \％$的系统不确定性的异常$WWγ$耦合获得的灵敏度估计值与实验结果进行了比较。我们的最佳敏感性将$ c_ {www}/{λ^2} $，$ c _ {\ widetilde {ww} ww}/λ^2 $，$ c_ {b}/c_ {b}/{λ^2} $，$ c_ {λ^2} $，$ c_ { $ c _ {\ widetilde {w}}/λ^2 $耦合为$ [ - 0.030; 0.025] \，\ text {tev}^{ - 2} $，$ [ - 0.014; 0.014] \，\ text {tev}^{ - 2} $，$ [ - 0.185; 0.187] \，\ text {tev}^{ - 2} $，$ [ - 0.187; 0.189] \，\ text {tev}^{ - 2} $和$ [ - 1.177; 1.097] \，\ text {tev}^{ - 2} $在Multi-Tev Muon撞机上，质量中心能量分别为30 TEV和90 AB $^{ - 1} $的集成光度。
The pursuit of discovery in particle physics has always required study at the highest possible energies. Multi-TeV muon colliders, which have important advantages, offer unprecedented potential for investigating new physics beyond the Standard Model. We extensively assume a range of center-of-mass energies from 3 to 30 TeV and a range of integrated luminosities from 1 to 90 ab$^{-1}$ for future multi-TeV muon colliders. We perform a phenomenological study of the anomalous $WWγ$ couplings via the process $μ^+ μ^-\,\rightarrow\,μ^+γ^* μ^-\,\rightarrow\,μ^+\ell^-ν_\ell \barν_\ell$ using a model-independent analysis in the effective field theory framework at multi-TeV muon colliders. The sensitivity estimates obtained for the anomalous $WWγ$ couplings at systematic uncertainties of $δ_{sys}=0$, $3$, $5\%$ are compared with the experimental results. Our best sensitivity limits at 95$\%$ confidence level for $c_{WWW}/{Λ^2}$, $c_{\widetilde{W}WW}/Λ^2$, $c_{B}/{Λ^2}$, $c_{W}/{Λ^2}$ and $c_{\widetilde{W}}/Λ^2$ couplings are $[-0.030; 0.025]\,\text{TeV}^{-2}$, $[-0.014; 0.014]\,\text{TeV}^{-2}$, $[-0.185; 0.187]\,\text{TeV}^{-2}$, $[-0.187; 0.189]\,\text{TeV}^{-2}$ and $[-1.177; 1.097]\,\text{TeV}^{-2}$ at the multi-TeV muon collider with center-of-mass energy of 30 TeV and integrated luminosity of 90 ab$^{-1}$, respectively.
