强子簇射中轻暗物质产生的新通道

New production channels for light dark matter in hadronic showers

Andrea Celentano, Luc Darmé, Luca Marsicano, Enrico Nardi

摘要:

强子簇射将它们的能量转移到电磁子簇射。我们表明,在这些子簇中的“二次”暗光子的产生是显着的,通常占主导地位的生产在低暗光子质量。然而,所产生的暗光子的能量比介子衰变产生的暗光子的能量低得多。我们说明这一点,半解析和通过蒙特卡罗模拟。现有的限制矢量介质的情况下,轻暗物质更新包括新的生产过程。

英文摘要:

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.
