Dimensional reduction as a source of stable mass in an expanded Yang-Mills theory
Krivoshchekov V. K. , Medvedev P. B.
A nontrivial dimensional reduction of an N = 1, d > 4 Yang-Mills theory which leads to a spontaneous symmetry breaking is accompanied by an activation of central charges in the algebra of the expanded supersymmetry in d = 4, so that the associated masses of the supermultiplets do not acquire quantum corrections.
