A note on Higgs decays into boson and
Rare decays with denoting the narrow or
resonances, such as or states, have been analyzed. Within
the standard model, these channels may proceed through the tree-level
transition with the virtual , and also loop-induced
process , followed by . Our analysis shows that,
for the bottomonium final states, the decay rate of from the
loop-induced process is small and the former transition gives the dominant
contribution; while, for the charmonium final states,
and induced by could be
comparable to the contribution given by the tree-level
transition.Comment: 6 pages, 2 figure
