dc.description.abstractA complete calculation of the rare three-body decay t → chγ is presented in the framework of the standard model. In the unitary gauge, such a calculation involves about 20 Feynman diagrams. We also calculate this decay in the general two-Higgs doublet model (model III), in which it arises at the tree level. While in the standard model the decay t → chγ is extremely suppressed, with a branching fraction of the order of 10-15 for a Higgs boson mass of the order of 115 GeV, in the model III it may have a branching ratio up to 10-5. We also discuss the crossed decay h → bs̄γ. © 2006 IOP Publishing Ltd.
