On SUSY breaking from NL/L SUSY relation

We show in two-dimensional space-time (d=2) the relation between an N=2 nonlinear supersymmetric (NLSUSY) model and an N=2 linear (L) SUSY Yang-Mills (SYM) theory with matter (N=2 LSUSY QCD theory). We give a new interpretation of four Nambu-Goldstone fermion (superon) contact terms, which emerge from an N=2 general SUSY QCD (composite) action, as mass terms for LSUSY supermultiplets and discuss the possible SUSY breaking mechanism in NL/L SUSY relation for SUSY gauge theories in d=2.
