摘要：

We study the heavy neutral scalar decays into standard model electroweak gauge bosons in the context of the littlest Higgs model. We focus our attention on the Phi(0). -> WW, gamma V processes induced at the one-loop level, with V = gamma, Z. Since the branching ratios of the F0. gV decays are. very suppressed, only the Phi(0) -> WW process is analyzed in the framework of possible experimental scenarios by using heavy scalar masses between 1.6 TeV and. 3.3 TeV. The branching ratio for the Phi(0) -> WW decay is of the order of 10(-3) throughout the interval 2 TeV < f < 4 TeV, which represents the global symmetry breaking scale of the theory. Thus,. the associated production cross section for pp. -> Phi X-0 WW. is estimated, finding around ten events for m(Phi)(0) approximate to 1.6 TeV at best.
