Detecting Boosted Dark Photons with Gaseous Detectors
AI总结:
本文研究keV级暗物质湮灭或衰变产生的增强暗光子信号,指出当前实验无法探测,但未来低背景气体探测器(如CYGNUS、NEXT、PANDAX-III)在湮灭截面大时可能敏感。
摘要:
我们寻找$\mathscr{O}$(keV)暗物质湮灭或衰变为$\mathscr{O}$(eV)暗光子的间接信号。这些暗光子将高度增强,其衰变长度大于银河系,并可能以依赖于光子-暗光子动力学混合参数和实验光学性质的速率被中微子或暗物质实验吸收。我们表明,当前实验无法探测新的参数空间,但未来具有低背景的大规模气体探测器(即CYGNUS、NEXT、PANDAX-III)在湮灭截面特别大时可能对此信号敏感。
英文摘要:
We search for indirect signals of $\mathscr{O}$(keV) dark matter annihilating or decaying into $\mathscr{O}$(eV) dark photons. These dark photons will be highly boosted and have decay lengths larger than the Milky Way, and can be absorbed by neutrino or dark matter experiments at a rate dependent on the photon-dark photon kinetic mixing parameter and the optical properties of the experiment. We show that current experiments can not probe new parameter space, but future large-scale gaseous detectors with low backgrounds (i.e. CYGNUS, NEXT, PANDAX-III) may be sensitive to this signal when the annihilation cross section is especially large.
