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.
