Why is the B --> η'X Decay Width So Large?
Abstract
A 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 Cabibbo favored b-->c¯cs process followed by the transition 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 B\(B-->η'+X\)~10-3 recently announced by CLEO. We stress the uniqueness of this channel for 0-+ gluonia search.
