# Possible decays of buttomonium

 P: 16 Hello, I need some help understanding the possible decays of buttomonium b$\bar{b}$. If I consider weak and electromagnetic interaction I could get final quark-anti-quark pairs, by simply annihilating b$\bar{b}$, or lepton-anti-lepton pairs (the neutral ones only with Zo resonance). So why are we looking for strong interaction? They are stronger, but also suppressed in this case, if we assume the mass of b$\bar{b}$ is below the one to from b-mesons. So is it the case that the three gluon involving OZI suppressed decay is still stronger then the weak and EM interaction? Thank you!
