Little Higgs theories were an outgrowth of dimensional deconstruction : In these theories, the gauge group has the form of a direct product of several copies of the same factor, for example SU (2) × SU (2). Each SU (2) factor may be visualized as the SU (2) group living at a particular point along an additional dimension of space. Consequently, many virtues of extra-dimensional theories are reproduced even though the little Higgs theory is 3+1 dimensional.
