Why is the B -> eta' X decay width so large ?

Abstract

New mechanism for the observed inclusive B -> η'X decay is suggested. We argue that the dominant contribution to this amplitude is due to the Cabbibo favored b -> \bar{c}cs process followed by the transition \bar{c}c -> η'. A large magnitude of the "intrinsic charm" component of η' is of critical importance in our approach. Our results are consistent with an unexpectedly large Br(B -> η'+X) \sim 10^{-3} recently announced by CLEO. We stress the uniqueness of this channel for 0^{-+} gluonia search.

Comments on a mixing model for intrinsic charm and pre-asymptotic effects and some references are added. Latex, 9 pages
