论文摘要
研究了CLIC对撞机在光线散射中的轴突样颗粒（ALP）的虚拟产生。假设ALP与Lagrangian中的CP-ODD项与光子相互作用，则计算差分和总截面。 95 \％C.L.给出了ALP质量及其耦合常数的排除区域。通过将我们的结果与现有的撞机界限进行比较，我们看到CLIC的ALP搜索具有巨大的物理潜力，可以搜索阿尔卑斯山，尤其是在Mass 1 Tev-2.4 TEV中，与Collision Energy $ \ sqrt {s} = 3000 $ GEV和Integrated Luminosity $ luminosity $ l = 5000 $ fb $^$^phot for comm comption for Commtion for Compton for compolisy unergy $ \ sqrt {s} = 3000 $ gev。特别是，我们的极限更强，最近在LHC的光线散射中获得了ALP产生的界限。
The virtual production of axion-like particles (ALPs) in the light-by-light scattering at the CLIC collider is studied. Both differential and total cross sections are calculated, assuming interaction of the ALP with photons via CP-odd term in the Lagrangian. The 95\% C.L. exclusion regions for the ALP mass and its coupling constant are given. By comparing our results with existing collider bounds, we see that the ALP search at the CLIC has a great physics potential of searching for the ALPs, especially, in the mass region 1 TeV -- 2.4 TeV, with the collision energy $\sqrt{s} = 3000$ GeV and integrated luminosity $L = 5000$ fb$^{-1}$ for the Compton backscattered initial photons. In particular, our limits are stronger that recently obtained bounds for the ALP production in the light-by-light scattering at the LHC.
