  We numerically and theoretically investigate how the softness of particles
affects the rheology of sheared dilute granular gases. We find that the kinetic
theory predicts the deviation of the flow curve from the Bagnold scaling, and
it works well below a certain shear rate when we compare with the simulation
results. It is also found that there is no theoretical solution above this
shear rate, which is because the energy loss due to inelastic collisions cannot
be balanced with the energy injection by the shear.
