摘要This is a sequel to our previous work on LHC phenomenology of the type II seesaw model in the nondegenerate case. In this work, we further study the pair and associated production of the neutral scalars H-0/A(0). We restrict ourselves to the so-called negative scenario characterized by the mass order M-H +/-+/- > M-H +/- > M-H0/A0, in which the H-0/A(0) production receives significant enhancement from cascade decays of the charged scalars H-+/-+/-, H-+/-. We consider three important signal channels-b (b) over barb gamma gamma, b (b) over bar tau(+)tau(-), b (b) over barl(+)l(-)E(T)-and perform detailed simulations. We find that at the 14 TeV LHC with an integrated luminosity of 3000 fb(-1), a 5s mass reach of 151, 150, and 180 GeV, respectively, is possible in the three channels from the pure Drell-Yan H(0)A(0) production, while the cascade-decay-enhanced H-0/A(0) production can push the mass limit further to 164, 177, and 200 GeV. The neutral scalars in the negative scenario are thus accessible at LHC run II.
