Higgs boson decay rate into gluons in a 5 dimensional calculable model
Abstract
Description
In an extension of the Standard Model with one compact extra dimension and N=1 supersymmetry, we compute the Higgs boson decay rate into two gluons, relevant to the Higgs production in hadronic collisions. We find that at one loop the decay width is significantly suppressed with respect to the SM. In particular, for a compactification radius 1/R=370 /pm 70 GeV and a Higgs mass m_H = 127 /pm 8 GeV we find it to be less than 15% of the SM result.
