Why is the B -> eta' X decay width so large ?
Abstract
New mechanism for the observed inclusive B -> eta' X decay is suggested. We argue that the dominant contribution to this amplitude is due to the Cabbibo favored b->c\bar{c}s process followed by the transition c\bar{c} ->eta'. A large magnitude of the "intrinsic charm" component of eta' is of critical importance in our approach. Our results are consistent with an unexpectedly large Br(B -> eta'+X) \sim 10^{-3} recently announced by CLEO. As a by-product, we also estimate the ratio \Gamma(B -> \eta_c(1S)+X)/ \Gamma(B -> J/\psi+X) \simeq 0.6 for eta_c(1S) production as well as the branching ratio for K^{\ast} meson: \Gamma(B -> eta'+K^{\ast}) \sim 2\Gamma(B->eta'+K). We stress the uniqueness of this channel for 0^{- +} gluonia search.Keywords
