Latest results on the Higgs boson discovery and investigation at the ATLAS-LHC

Nguyễn Anh Kỳ anh Nguyễn Thị Hồng Vân

On 04 July 2012, ATLAS and CMS, the two biggest LHC collaborations, announced the discovery of a new boson with a mass around 125 GeV. With the preliminarily delivered information, this particle resembles the Higgs boson (of the standard model) playing a key role in the symmetry breaking mechanism generating particle masses in the standard model. To con rm if the newly discovered particle is really the Higgs boson it is necessary to do further and detailed investigations to precisely determine its nature and properties. Here we will summarize some of the latest results of these investigations. If the new particle is the Higgs boson, the standard model will get the full recognition as a very successful model, otherwise, another model may be needed to replace the standard model in order to explain all the observed phenomena. The results obtained by ATLAS (and CMS) for last two years have almost shown that this new particle can be identified with the Higgs boson.
