Answer

$J/\Psi (3097)$ and $\Upsilon(9460)$.

Work Step by Step

The relative strengths of the fundamental forces play a factor in the rate of decay. Decays that proceed via the electromagnetic interaction, for example, proceed more slowly than those that happen via the strong interaction, but more quickly than those that proceed via the weak interaction. Table 32-4 lists the lifetimes for some heavy hadrons. The particle decays that occur via the electromagnetic interaction are $J/\Psi (3097)$ and $\Upsilon(9460)$.
