Universal properties of superconformal OPEs for 1/2 BPS operators in
Sergio Ferrara, Emery Sokatchev
We give a general analysis of OPEs of 1/2 BPS superfield operators for the superconformal algebras OSp(8/4,R), PSU(2,2), F and OSp() which underlie maximal…
(2,0) Superconformal OPEs in D=6, Selection Rules and Non-renormalization Theorems
B. Eden, S. Ferrara, E. Sokatchev
We analyse the OPE of any two 1/2 BPS operators of (2,0) SCFT by constructing all possible three-point functions that they can form with another, in general long operator. Such…
On the OPE of 1/2 BPS Short Operators in N=4 SCFT
B. Eden, E. Sokatchev
The content of the OPE of two 1/2 BPS operators in N=4 SCFT is given by their superspace three-point functions with a third, a priori long operator. For certain 1/2 BPS short s…
On Non-renormalization and OPE in Superconformal Field Theories
G. Arutyunov, B. Eden, E. Sokatchev
The OPE of two N=2 R-symmetry current (short) multiplets is determined by the possible superspace three-point functions that two such multiplets can form with a third, a priori lon…
Exceptional non-renormalization properties and OPE analysis of chiral four-point functions in N=4 SYM_4
G. Arutyunov, B. Eden, A. C. Petkou +1
We show that certain classes of apparently unprotected operators in N=4 SYM_4 do not receive quantum corrections as a consequence of a partial non-renormalization theorem for the 4…
