Description

The gauge coupling constant unification at the low (O(TeV)) scale can be obtained just in four dimensions, without the help of the power like renormalization group evolution in extra dimensions, due to the presence of some extra particle states at intermediate scales. We show explicit examples of such extra states in the range of 100 GeV - 1 TeV which can easily be observed on future colliders and can have an important impact on the particle phenomenology. The problems of the low scale grand unification and proton stability are also discussed. (author)
