摘要：

We comment on a discrepancy in sign between two recent papers [C. S. Lim, T. Morozumi, and A. I. Sanda, Phys. Lett. B 218, 343 (1989); N. G. Deshpande, J. Trampetic, and K. Panose, Phys. Rev. D 39, 1461 (1989)]; regarding the resonance contributions to the decay b --> sl+l-. We find that the problem can be settled by considering the unitarity limit in the Argand plot of the transition amplitude.
