摘要：

We study two-body decays of a new neutral pseudoscalar into standard model gauge bosons within the context of the Littlest Higgs model. The Phi(P) -> WW, VV, gg processes induced at the one-loop level, with V = gamma, Z, are considered. Since the branching ratios of the Phi(P) -> VV decays result were very suppressed, only the Phi(P) -> WW, gg processes are thoroughly studied. The branching ratios for the Phi(P) -> gg and Phi(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 Phi(P) boson via gluon fusion at the LHC is estimated.
