Abstract
We study the decay width of the inclusive process b --> s g g in the two Higgs doublet model with three-level flavor changing neutral currents (model III). We analyse the dependencies of the differential decay width to the s- quark energy Es and model III parameters, charged Higgs mass mH± and Yukawa coupling \bar{x}N,bbD. We observe that there exist a considerable enhancement in the decay width for the relevant process. This enhancement can be reduced by choosing C7eff as negative or increasing the lower bound of mH± to the large values. This is an interesting result which gives an idea on the mass mH± and sign of C7eff.
