A note on the perturbative properties of BPS operators
We discuss the perturbative behavior of the 1/2 BPS operators in N=2 SCFT on the example of two very similar quadrilinear composite operators made out of hypermultiplets. An explicit one-loop computation shows that one of them is protected while the other acquires an anomalous dimension. Although bo...
