摘要：
We present a fit to observational data in an asymmetric self-interacting dark matter model using our recently calculated cross sections that incorporate both t -channel and u -channel exchanges in the scattering of identical particles. We find good fits to the data ranging from dwarf galaxies to galaxy clusters and equivalent relative velocities from-20 km/s to greater than or similar to 103 km/s. We compare our results with previous fits that used only t -channel exchange contributions to the scattering.
