论文摘要
在这封信中，我们建议在超疗法$ pbpb $碰撞中的$γγ$相互作用产生的尖酸衰减中搜索深色光子。估计横截面考虑了对吸收校正和核外形的准确处理。考虑到LHC，高光度LHC和高能量LHC以及未来的圆形碰撞器的预期亮度，提出了事件速率的预测。我们的结果表明，未来对超疗养重离子碰撞中暂停产生的实验分析对于探测深色光子的产生并限制其特性很有用。
In this letter we propose the search of dark photons in the decay of pions produced by $γγ$ interactions in ultraperipheral $PbPb$ collisions. The cross section is estimated considering an accurate treatment for the absorptive corrections and for the nuclear form factor. Predictions for the event rates are presented considering the expected luminosities for the LHC, High -- Luminosity LHC and High -- Energy LHC as well as for the Future Circular Collider. Our results indicate that a future experimental analysis of the pion production in ultraperipheral heavy ion collisions can be useful to probe the dark photon production and constrain its properties.
