固定目标实验中ALP搜索的新观点

A fresh look at ALP searches in fixed target experiments

Lucian Harland-Lang, Joerg Jaeckel, Michael Spannowsky

摘要:

大量的高功率质子束可用或将在不久的将来上线。这为新的固定目标实验,特别是寻找新的物理学提供了令人兴奋的机会。在本说明中,我们将调查这些光束,并考虑其潜在的发现新的物理形式的轴子粒子,确定有前途的位置和设置。为了实现这一目标,我们提出了一个显着改进的计算生产轴子样粒子的质子在核上的相干散射,有效的较低ALP质量和/或束能量。我们还为这个过程提供了一个新的公开可用的工具:Alpaca Monte Carlo生成器。这将影响基于此过程的正在进行和计划的检索。

英文摘要:

A significant number of high power proton beams are available or will go online in the near future. This provides exciting opportunities for new fixed target experiments and the search for new physics in particular. In this note we will survey these beams and consider their potential to discover new physics in the form of axion-like particles, identifying promising locations and set ups. To achieve this, we present a significantly improved calculation of the production of axion-like particles in the coherent scattering of protons on nuclei, valid for lower ALP masses and/or beam energies. We also provide a new publicly available tool for this process: the Alpaca Monte Carlo generator. This will impact ongoing and planned searches based on this process.
