field realizations of the non - critical W 2 , s strings based on the linear W 1 , 2 , s algebras ∗
In this paper, we investigate the new spinor field realizations of the W 2,s algebras, making use of the fact that the W 2,s algebras can be linearized through the addition of a spin-1 current. We then use these new realizations to build the nilpotent BRST charges of the spinor non-critical W 2,s strings. The cases of s = 3 and 4 are discussed in detail. 2 1. Introduction As is well known, W al...
متن کامل5 Spinor Field Realizations of Non - critical W 2 , s Strings ∗
In this paper, we construct the nilpotent Becchi-Rouet-StoraTyutin(BRST ) charges of spinor non-critical W2,s strings. The cases of s = 3, 4 are discussed in detail, and spinor realization for s = 4 is given explicitly. The BRST charges are graded. PACS numbers: 11.25.Sq, 11.10.-z, 11.25.Pm.
متن کاملA Derivation of the BRST Operator for Non - Critical W Strings
We derive the recently proposed BRST charge for non-critical W strings from a Lagrangian approach. The basic observation is that, despite appearances, the combination of two classical " matter " and " Toda " w 3 systems leads to a closed modified gauge algebra, which is of the so-called soft type. Based on these observations , a novel way to construct critical W 3 strings is given.
متن کاملEmbedding of the Bosonic String into the W 3 String
We investigate new realisations of the W 3 algebra with arbitrary central charge, making use of the fact that this algebra can be linearised by the inclusion of a spin-1 current. We use the new realisations with c = 102 and c = 100 to build non-critical and critical W 3 BRST operators. Both of these can be converted by local canonical transformations into a BRST operator for the Virasoro string...

We show how to relate the parafermions that occur in the W 3 string to the standard construction of parafermions. This result is then used to show that one of the screening charges that occurs in parafermionic theories is precisely the non-trivial part of the W 3 string BRST charge. A way of generalizing this pattern for a W N string is explained. This enables us to construct the full BRST char...
