This talk will present Sweet-Parker type scaling arguments in thecontext of collisionless, hyper-resistive, Hall magnetohyrdodynamics(MHD). The predicted steady state scalings are consistent with those found by Chacon et al. PReLett. 99, 235001 (2007)], and similar to therecent findings of Uzdensky, [Phys. Plas. 16, 040702 (2009)]. However,as with those studies, no prediction of electron dissipation regionlength is made. Numerical experiments confirm that both cusp like andmodestly more extended geometries are realizable. Importantly though,the length of the electron dissipation region, which is taken as aparameter by the above studies, is found clearly to depend on the levelof hyper-resistivity. Although hyper-resistivity can produce somewhatmore extended electron dissipation regions, the length of the regionremains smaller than one ion skin depth for the largest values ofhyper-resistivity considered here. In our simulations, the thickness ofthe dissipation region scales in a similar way as the length, so thatthe reconnection rate is not strongly sensitive to the level of hyperresistivity. Furthermore, the length of the electron dissipation regionis found to depend on electron inertia as well, scaling like(m_e/m_i)^1/3. However, the thickness of the region appears to scale inthe same way, so that the aspect ratio also remains independent of themass ratio. The limitations of scaling theories that do not predict thelength of the electron dissipation region are emphasized.
