| Research Abstract |
Existence of Higgs particles was predicted by the standard model but they have not yet been discovered by previous experiments. The ATLAS experiment at the LHC accelerator constructed at CERN near Geneva, is aiming the discovery. The experimental data taken by ATLAS are analyzed by using a computing grid, which is globally deployed for the first time in the world. Analysis infrastructure has been developed using the ATLAS regional analysis center system installed at the University of Tokyo. In order to improve the discovery potential of the Higgs particles, a new analysis algorithm has been established, which can find them with 10 times higher sensitivity. Now the ATLAS experiment is accumulating data intensively and the discovery is expected in near future.
