| Abstract | A new boson around 125 GeV without specific spin has been observed by both ATLAS and CMS at the LHC. Since its decay into a diphoton excludes the spin-1 case by the Landau-Yang theorem, it leaves 0 or 2 as the possible lowest spin for the new boson. Instead of the well-established spin-0 Higgs-like boson, we take this new boson to be a spin-2 massive graviton-like particle denoted as G, which exists copiously in extra-dimension theories, and concentrate on its phenomenology. In particular, we calculate the three-body decays of G -> Vf (f) over bar' with V and f((')) the gauge boson and fermions in the standard model (SM) and compare our results with those of the SM Higgs boson. The couplings between G and Vs are also estimated by fitting the data. A new observable that can distinguish G from the Higgs is proposed. (C) 2013 Elsevier B.V. All rights reserved. |
