研究通过RHICf实验测量了六个伪快速度区域的光子产额，与LHCf在$\sqrt{s}$=7和13 TeV的结果进行比较，并验证了Feynman标度律和多个模型预测的一致性。

摘要：

本研究报告了在$\sqrt{s}$=510 GeV的pp碰撞中，通过RHICf实验测量的六个伪快速度区域（6.1 < $η$ < 6.5, 6.5 < $η$ < 7.0, 7.0 < $η$ <7.5, 7.5 < $η$ <8.0, 8.0 < $η$ < 8.5, 和$η$ > 8.5）的光子总微分产额。此外，还获得了与LHCf在$\sqrt{s}$=7和13 TeV结果相同的$x_F$-$p_T$相空间覆盖区域的产额，并进行了比较。考虑到不确定性，结果与Feynman标度律以及EPOS-LHC、QGSJET-II-04、Sibyll 2.3d和DPMjet-III 2019.1模型预测一致，尽管某些模型表现出弱的碰撞能量依赖性。

英文摘要：

This study reported the inclusive differential production cross-section of photons in six pseudorapidity regions: 6.1 < $η$ < 6.5, 6.5 < $η$ < 7.0, 7.0 < $η$ <7.5, 7.5 < $η$ <8.0, 8.0 < $η$ < 8.5, and $η$ > 8.5, measured through the RHICf experiment with pp collisions at $\sqrt{s}$ = 510 GeV conducted in June 2017. In addition, the cross-sections in the three regions of the $x_F$-$p_T$ phase space coverage that are same as those of the LHCf results at $\sqrt{s}$ = 7 and 13 TeV were obtained and compared. Considering the uncertainties, the results were observed to be consistent with both the Feynman scaling law and the model predictions of EPOS-LHC, QGSJET-II-04, Sibyll 2.3d, and DPMjet-III 2019.1, although certain models exhibited weak collision energy dependencies.
