On the uniqueness of the effective Lagrangian for N = 2 SQCD
/ Authors
/ Abstract
The low-energy effective Lagrangian for N = 2 SU(2) supersymmetric Yang-Mills theory coupled to NF < 4 massless matter fields is derived from the BPS-mass formula using asymptotic freedom and assuming that the number of strong coupling singularities is finite.
