Unified Models and Collider Experiments

Abstract

Future collider experiments are expected to discover new physics beyond the Standard Model and Higgs boson. As a new physics beyond the Standard Model, we consider unified models which give some unified picture for some parts of the Standard Model. Although unified models usually take place at very high energies, the future collider experiments may provide us some indirect information by precise measurements of particle masses and couplings. A class of unified models predicts some exotic particles. Once the future colliders discover such exotic particles, we obtain the direct information on the unified models.
