论文摘要
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 $\sqrt{s}$ = 2017年6月进行的510 GEV。此外,获得了$ x_f $ - $ p_t $相位空间覆盖范围的三个区域的横截面,与$ \ sqrt {s} $ = 7和13 TEV相同的LHCF结果相同。考虑到不确定性,观察到结果与Feynman缩放定律和EPOS-LHC,QGSJET-II-04,SIBYLL 2.3d和DPMJET-III 2019.1的模型预测一致,尽管某些模型表现出较弱的碰撞能量依赖性。
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.
