Non-spectator contribution: A mechanism for inclusive B-> X_s eta' and exclusive B-> K(*) eta' decays
M. R. Ahmady, E. Kou, A. Sugamoto
We propose a mechanism which can explain the large BR(B-> X_s eta')~ 10^(-3) observed by CLEO. In this mechanism, eta' is produced by the fusion of two gluons, one from QCD penguin…

Intermediate psuedoscalar resonance contributions to B->X_s photon photon
Mohammad R. Ahamdy, Emi Kou, Akio Sugamoto
We calculate the decay rate B-> X_s photon photon via intermediate psuedoscalar charmonium eta_c. This process is thought to be the main long-distance contribution which dominates…
