Abstract：
We investigate the non-leptonic weak interaction in magnetic field and discuss the improvement of the previous method to analytically work out the rate for weak field case. Our result easily goes over to the field-free limit. Then we calculate the reaction rate in strong magnetic field where the charged particles are confined to the lowest Landau level. A strong magnetic field strongly suppress the rate, which will be foreseen to affect viscous dynamics in SQM. We also derive a few approximation formulae under given conditions that can be conveniently applied.
