The b--> s g g decay in the general two Higgs doublet model

Original · EN

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 ξN,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 and increasing the lower bound of mₕ± to the large values, such as 800 GeV. This is an interesting result which gives an idea on the mass mₕ± and sign of C₇eff.
