An overview of elementary particle physics around the Standard Model and its extensions

The Standard Model (SM) has been checked steadily in this way. Furthermore, the Large Hadron Collider (LHC) at CERN has been operated since 2008. It is hoped that the Higgs boson and exotic particles such as supersymmetric (SUSY) particles, which are not the members of the SM, will be discovered. On the other hand, various models have been proposed theoretically, which may unify the strong and electroweak interactions, and even gravity. In such models, the problems in the SM may be solved. This article outlines the theoretical and experimental situations around the SM and its extensions
