Aa. Petrov, HOW TO TRAP A NONSTANDARD PENGUIN - ISOSPIN SYMMETRY VIOLATIONS IN B-DECAYS WITH ENHANCED CHROMOMAGNETIC DIPOLE OPERATOR, Physics letters. Section B, 399(1-2), 1997, pp. 172-176
A recently proposed non-standard model solution to the problem of low
semileptonic branching ratio B-SL which suggests a large branching rat
io for the decay b --> sg is critically examined. It is shown that the
effects of the enhanced chromomagnetic dipole operator might lead to
significant violations of isospin symmetry in rare radiative decays of
B-mesons. (C) 1997 Published by Elsevier Science B.V.
