We derive an analytical expression for the scattering amplitude of two ultracold atoms of arbitrary spin and with general spin-orbit (SO) coupling, on the basis of our recent work (Phys. Rev. A 86, 053608 (2012)). The same approach can also be applied to calculate the two-body bound state of SO-coupled ultracold atoms. Moreover, we predict a new kind of scattering resonance that is induced by SO coupling. We also carefully examine the renormalization relation of effective contact interaction with momentum cutoff for the ultracold atoms with SO coupling.
