Final state interaction effects on the eta(b) => J/psi J/psi decay
Abstract
Description
We study the effects of final state interactions on the eta(b) => J/psi J/psi decay. In particular, we discuss the effects of the annihilation of eta(b) into two charmed meson and their rescattering into J/psi J/psi. We find that the inclusion of this contribution may enhance the short-distance branching ratio up to about 2 orders of magnitude.
