  "abstract": "A collisionless, low-$β$ plasma undergoing strong sub-Alfvénic turbulence is expected to form a broad hierarchy of reconnecting current sheets immersed in a strong guide magnetic field. If the reconnecting field strength of a sheet scales with its length as a power law of index $κ$, and the number of sheets per unit interval of sheet length decreases as a power law of index $x$, the current-sheet ensemble injects nonthermal particles with a power-law energy spectrum $\\propto γ^{-s}$, where $s = 1 + (x-2)/(1 + κ)$. The spectrum is hard ($s < 2$) when the longest sheets deliver most of the injected energy, which requires $x < 3 + κ$. Past numerical studies have measured $2 \\lesssim x \\lesssim 3.3$, and the scalings of intense current sheets support $κ\\gtrsim 0$, resulting in $1 \\lesssim s \\lesssim 2.3$. This injection may yield flat or mildly steep radio spectra in optically thin sources and hard ion spectra in the coronae of active galactic nuclei.",
