论文摘要
研究了由轴突样颗粒（ALP）引起的，具有初始极化的康普顿反向散射光子的逐光（LBL）散射。假设伪尺度ALP与光子的CP耦合，则计算了总横截面。 95 \％C.L.提出了ALP质量$ M_A $的排除区域及其耦合常数$ f $。将结果与先前获得的非极化情况的Clic界限进行了比较。结果表明，该区域中两极分化的光束的$ f $界限$ m_a = 1000 \ mathrm {\ gev} - 2000 \ MathRm {\ gev} $，碰撞能量3000 GEV和集成的亮度4000 fb $^{ - 1} $，平均是1.5倍的范围，均超过1.5倍的范围。因此，我们的CLIC界限比所有当前排除区域都强，$ M_A> 80美元GEV。特别是，它们比来自LHC的ALP介导的LBL散射所遵循的极限更具限制性。
The light-by-light (LBL) scattering with initial polarized Compton backscattered photons at the CLIC, induced by axion-like particles (ALPs), is investigated. The total cross sections are calculated, assuming CP-even coupling of the pseudoscalar ALP to photons. The 95\% C.L. exclusion region for the ALP mass $m_a$ and its coupling constant $f$ is presented. The results are compared with previously obtained CLIC bounds for the unpolarized case. It is shown that the bounds on $f$ for the polarized beams in the region $m_a = 1000 \mathrm{\ GeV} - 2000 \mathrm{\ GeV}$, with the collision energy 3000 GeV and integrated luminosity 4000 fb$^{-1}$, are on average 1.5 times stronger than the bounds for the unpolarized beams. Herewith, our CLIC bounds are stronger than all current exclusion regions for $m_a > 80$ GeV. In particular, they are more restrictive than the limits which follow from the ALP-mediated LBL scattering at the LHC.
