Description
In this work R-symmetry defined in Wess-Zumino model is determined to be broken spontaneously within broken supersymmetric vacuum according to O'Raifeartaigh potential containing scalar fields of R-charges of 0 or 2. The analysis is done on Coleman-Weinberg effective potential at one-loop level. We find that there can be gauge symmetry breaking and R-symmetry breaking if $m_{X}^2<0$ and scalar field with R-charge other than 0 or 2 exists. The gaugino mass at one loop is in the order of $\Lambda\ln\Lambda$ scale but the renormailization is required.
