Prospects of physics beyond the standard model: Supersymmetry

Despite the success of the standard model of particle physics, there are reasons to expect new physics beyond it. Supersymmetric extension is a promising possibility, which solves the fine-tuning problem inherent to the origin of the electroweak scale in the standard model. It also provides a promising candidate for dark matter. The verification of low-energy supersymmetry in forthcoming experiments will lead us to a new paradigm of particle physics, in particular, it may open up the road to the unification of forces.
