Higgs two-gluon decay and the top-quark chromomagnetic moment
We obtain the effective interaction ${\cal L}_{hgg}$, which is driven by the fluctuations of the top quark, as a function of the top quark chromomagnetic factor $\kappa_t$. We show that for $\kappa_t\ne 2$ the Higgs-to-two gluon, $h\to gg$, decay rate is always significantly suppressed as compared t...
