Four - Point Functions of Chiral Primary Operators in N=4 SYM
B. Eden, C. Schubert, E. Sokatchev
We discuss recent progress in the determination of correlators of chiral primary operators in N=4 Super-Yang-Mills theory, based on a combination of superconformal covariance argum…
Superconformal interpretation of BPS states in AdS geometries
Sergio Ferrara, Emery Sokatchev
We carry out a general analysis of the representations of the superconformal algebras SU(2,2/N), OSp(8/4,R) and OSp(8^*/4) and give their realization in superspace. We present a co…
Representations of (1,0) and (2,0) superconformal algebras in six dimensions: massless and short superfields
Sergio Ferrara, Emery Sokatchev
We construct unitary representations of (1,0) and (2,0) superconformal algebras in six dimensions by using superfields defined on harmonic superspaces with coset manifolds USp(2n)/…
Short representations of SU(2,2/N) and harmonic superspace analyticity
S. Ferrara, E. Sokatchev
We consider the harmonic superspaces associated to SU(2,2/N) superconformal algebras. For arbitrary N, we show that massless representations, other than the chiral ones, correspond…
Shortening of primary operators in N-extended SCFT_4 and harmonic-superspace analyticity
L. Andrianopoli, S. Ferrara, E. Sokatchev +1
We present the analysis of all possible shortenings which occur for composite gauge invariant conformal primary superfields in SU(2,2/N) invariant gauge theories. These primaries h…
Chiral fermion action with (8,0) worldsheet supersymmetry
E. Ivanov, E. Sokatchev
We propose an action describing chiral fermions with an arbitrary gauge group and with manifest worldsheet supersymmetry. The form of the action is inspired by and adapted…
