On SUSY breaking from NL/L SUSY relation

摘要

We show in two-dimensional space–time (d=2) the relation between anN=2nonlinear supersymmetric (NLSUSY) model and anN=2linear (L) SUSY Yang–Mills (SYM) theory with matter (N=2LSUSY QCD theory). We give a new interpretation of four Nambu–Goldstone fermion (superon) contact terms, which emerge from anN=2general 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 ind=2.
