论文摘要
HADRONES阵雨将相关量的能量转移到电磁亚表演者。我们表明，在这些子肖像机中，“次级”深色光子的产生很重要，通常在低暗光子质量下占主导地位。然而，所得的深色光子的能量要比介质衰减的光子少得多。我们通过半分析和通过蒙特卡洛模拟说明了这一点。通过新生产过程的包含，对矢量介绍者场景的现有限制进行了更新。
Hadronic showers transfer a relevant amount of their energy to electromagnetic subshowers. We show that the generation of "secondary" dark photons in these sub-showers is significant and typically dominates the production at low dark photon masses. The resulting dark photons are however substantially less energetic than the ones originating from mesons decay. We illustrate this point both semi-analytically and through Monte Carlo simulations. Existing limits on vector-mediator scenarios for light dark matter are updated with the inclusion of the new production processes.
