    • Our approach is entirely different from that of C. Boyd, B. Grinstein, and R. Lebed, Phys. Rev. Lett.74, 4603 (1995). In this reference, bounds on the form factors are derived by computing a two-point function in PQCD at (Formula presented). However, at these values of (Formula presented), large corrections are likely to exist that would affect the bounds. On the other hand, computing at large spacelike values of (Formula presented), where PQCD should be trusted the most in the computation of the vacuum polarization involved, considerably loosens the bounds.

The fact that the resulting differential decay rate has a zero in the physical region signals the need for large corrections and shows that the perturbative calculation is not under control.
