Obviously, if susy is there at the lhc scale, the lhc will eventually be discovering fireworks of new effects (susy is also the most attractive realistic possibility for the experimenters) - all the … But n = 4 n = 4 is a scft, and the r-charge appears in the susy algebra on the r. h. s. Of the anticommutators {s, q} {s, q} and cannot be anomalous without breaking scft.
