A new n = 6 superconformal algebra

TL;DR: In this paper, a new N = 6 superconformal algebra which extends the Virasoro algebra by the SO 6 current algebra, by 6 odd primary fields of conformal weight 3/2 and by 10 odd primary field of conformally weight 1/2, is presented.
Abstract: In this paper we construct a newN = 6 superconformal algebra which extends the Virasoro algebra by theSO 6 current algebra, by 6 odd primary fields of conformal weight 3/2 and by 10 odd primary fields of conformal weight 1/2. The commutation relations of this algebra, which we will refer to asCK 6, are represented by short distance operator product expansions (OPE). We constructCK 6, as a subalgebra of theSO(6) superconformal algebra K6, thus giving it a natural representation as first order differential operators on the circle withN = 6 extended symmetry. We show thatCK 6 has no nontrivial central extensions.

TL;DR: Conformal algebra is an axiomatic description of the operator product expansion (or rather its Fourier transform) of chiral fields in a conformal field theory.
Abstract: Conformal algebra is an axiomatic description of the operator product expansion (or rather its Fourier transform) of chiral fields in a conformal field theory. This is a review of recent developments in the subject.

TL;DR: In this paper, simple complex Lie superalgebras of vector fields on "supercircles" are defined and described, and three nontrivial cocycles on the N=4 extended Neveu-Schwarz and Ramond superalgebra are presented.
Abstract: We define and describe simple complex Lie superalgbras of vector fields on "supercircles" - simple stringy superalgebras. There are four series of such algebras and four exceptional stringy superalgebras. The 13 of the simple stringy Lie superalgebras are distinguished: only they have nontrivial central extensions; since two of the distinguish algebras have 3 nontrivial central extensions each, there are exactly 16 superizations of the Liouville action, Schroedinger equation, KdV hierarchy, etc. We also present the three nontrivial cocycles on the N=4 extended Neveu-Schwarz and Ramond superalgebras in terms of primary fields and describe the "classical" stringy superalgebras close to the simple ones. One of these stringy superalgebras is a Kac-Moody superalgebra G(A) with a nonsymmetrizable Cartan matrix A. Unlike the Kac-Moody superalgebras of polynomial growth with symmetrizable Cartan matrix, it can not be interpreted as a central extension of a twisted loop algebra.The stringy superalgebras are often referred to as superconformal ones. We discuss how superconformal stringy superalgebras really are.

TL;DR: In this article, a classification of superconformal algebras is given, based on the classification of all connected subgroups of SOn(C) which act transitively on the quadric (v, v) = 1.
Abstract: A classification of “physical” superconformal algebras is given. The list consists of seven algebras: the Virasoro algebra, the Neveu-Schwarz algebra, theN = 2,3 and 4 algebras, the superalgebra of all vector fields on theN = 2 supercircle, and a new algebraCK6 constructed in [3]. The proof relies heavily on the classification of all connected subgroups ofSOn(C) which act transitively on the quadric (v, v) = 1.
