SPring-8强X射线束寻找副光子的结果
Results of a Search for Paraphotons with Intense X-ray Beams at SPring-8
摘要:
利用SPring-8上的强X射线束线进行了对准光子或隐藏的U(1)规范玻色子的搜索。在这次搜索中使用了“光透墙”技术。未观察到超过背景的事件。对$0.04\ {\rm eV}<m_{γ^{\prime}} < 26\ {\rm keV}$的光子-准光子混合角$χ< 8.06\times 10^{-5}\ (95%\ {\rm C.L.})$给出了严格的约束。
英文摘要:
A search for paraphotons, or hidden U(1) gauge bosons, is performed using an intense X-ray beamline at SPring--8. "Light Shining through a Wall" technique is used in this search. No excess of events above background is observed. A stringent constraint is obtained on the photon--paraphoton mixing angle, $χ< 8.06\times 10^{-5}\ (95%\ {\rm C.L.})$ for $0.04\ {\rm eV}<m_{γ^{\prime}} < 26\ {\rm keV}$.
