Heavy neutral pseudoscalar decays into gauge bosons in the Littlest Higgs model

We study two-body decays of a new neutral pseudoscalar into standard model gauge bosons within the context of the Littlest Higgs model. The Φ P → WW , VV , gg processes induced at the one-loop level, with V = γ , Z , are considered. Since the branching ratios of the Φ P → VV decays result were very...

Description
Summary:We study two-body decays of a new neutral pseudoscalar into standard model gauge bosons within the context of the Littlest Higgs model. The Φ P → WW , VV , gg processes induced at the one-loop level, with V = γ , Z , are considered. Since the branching ratios of the Φ P → VV decays result were very suppressed, only the Φ P → WW , gg processes are thoroughly studied. The branching ratios for the Φ P → gg and Φ P → WW decays are of the order of 10−5 and 10−7, respectively, for f around 3 TeV, which represents the global symmetry breaking scale of the theory. The production cross section of the Φ P boson via gluon fusion at the LHC is estimated.
