The distribution of reconnection rates in a turbulent plasma was previously studied using incompressible resistive MHD and was found to scale according to asymmetric Sweet-Parker theory [Servidio et al., 2009, 2010]. Turbulence was found to enhance reconnection rate drastically in these simulations, even when kinetic effects are not included. Here, we study magnetic reconnection in a turbulent environment using kinetic ion and fluid electron simulations (Hybrid simulations). The distribution of reconnection rates is re-examined to understand the effect of both turbulence and ion kinetic physics (including e.g., Hall physics. For a Hall MHD approach to the same topic, see the abstract by Donato et al.) on reconnection rate. The interaction of many magnetic islands and the cascade of energy are also re-examined within the frame of the hybrid model.
