A note on the perturbative properties of BPS operators
Gleb Arutyunov, Emery Sokatchev
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 explic…
Non-protected operators in N=4 SYM and multiparticle states of AdS_5 SUGRA
G. Arutyunov, S. Penati, A. C. Petkou +2
We study a class of non-protected local composite operators which occur in the R symmetry singlet channel of the OPE of two stress-tensor multiplets in {\cal N}=4 SYM. At tree leve…
Conformal fields in the pp-wave limit
G. Arutyunov, E. Sokatchev
The pp-wave (Penrose limit) in conformal field theory can be viewed as a special contraction of the unitary representations of the conformal group. We study the kinematics of confo…
Conformally coupled supermultiplets in four and five dimensions
Sergio Ferrara, Emery Sokatchev
We obtain by superfield methods the exceptional representations of the OSp(2N/4,R) and SU(2,2/1) superalgebras which extend to supersingletons of SU(2,2/2N) and F(4), respectively.…
Implications of Superconformal Symmetry for Interacting (2,0) Tensor Multiplets
G. Arutyunov, E. Sokatchev
We study the structure of the four-point correlation function of the lowest-dimension 1/2 BPS operators (stress-tensor multiplets) in the (2,0) six-dimensional theory. We first dis…
