| 英文摘要 | On-going Higgs searches in the light mass window are of vital importance for testing the Higgs mechanism and probing new physics beyond the standard model (SM). The latest ATLAS and CMS searches for the SM Higgs boson at the LHC (7TeV) found some intriguing excesses of events in the gamma gamma/VV* channels (V - Z, W) around the mass-range of 124 - 126 GeV. We explore a possible explanation of the gamma gamma and VV* signals from the light CP-odd Higgs A(0) or CP-even Higgs h(0) from the general two-Higgs-doublet model with fourth-family fermions. We demonstrate that by including invissible decays of the higgs boson A(0) or h(0) to fouth-family neutrinos, the predicted gamma gamma and VV* signals can explain the observed new signatures at the LHC, and will be further probed by the forthcoming LHC runs in 2012. |
