Abstract: Previous 2D simulations of reconnection using a standard model of initially antiparallel magnetic fields
have detected electron jets outflowing from the x point into the ion outflow exhausts. Associated with
these jets are extended ‘‘outer electron diffusion regions.’’ New PIC simulations with an ion to electron
mass ratio as large as 1836 (an Hþ plasma) now show that the jets are strongly deflected and the outer
electron diffusion region is broken up by a very weak out-of-plane magnetic guide field, even though the
diffusion rate itself is unchanged. Jet outflow and deflection are interpreted in terms of electron dynamics
and are compared to recent measurements of jets in the presence of a small guide field in Earth’s
