Apart from explaining their error we summarize the results of a more detailed work that demonstrates explicitly that R parity can break spontaneously at a scale anywhere in the range 10 GeV to 1 Tev in a simple extension of the minimal SUSY standard model proposed previously.4 pages and 1 figureHigh Energy Physics - Phenomenologytext
