Abstract

We propose searching for dark photon signals in the decay channel of $\eta$ mesons, specifically through the leptonic decay ($A^\prime \to e^+e^-(\mu^+\mu^-)$) observable in photon-photon interactions during ultra-peripheral heavy-ion collisions. We estimate the total cross-section for dark photon production in ultra-peripheral $PbPb$ collisions at current and future hadron colliders. Our findings support the potential for detecting dark photon signals at the LHC, High-Luminosity LHC, High-Energy LHC, and the Future Circular Collider.

在高能碰撞中估算暗光子的$\eta$衰变产生量
我们提议在$\eta$介子的衰变通道中寻找暗光子信号,特别是通过在超外围重离子对撞期间的光子-光子相互作用中可观测到的轻子衰变($A^\prime \to e^+e^-(\mu^+\mu^-)$ )。我们估算了在当前和未来的强子对撞机上超外围$PbPb$对撞中暗光子产生的总截面。我们的研究结果支持在大型强子对撞机、高亮度大型强子对撞机、高能量大型强子对撞机和未来环形对撞机上探测暗光子信号的潜力。本作品内容可根据知识共享署名 3.0 许可条款使用。对本作品的任何进一步传播都必须注明作者、作品名称、期刊引文和 DOI。文章由 SCOAP3 资助,由中国物理学会、中国科学院高能物理研究所、中国科学院近代物理研究所和 IOP Publishing Ltd. 授权出版。
