Spinor Field Realizations of the half-integer W2,s Strings
نویسنده
چکیده
The grading Becchi-Rouet-Stora-Tyutin (BRST) method gives a way to construct the integer W2,s strings, where the BRST charge is written as QB = Q0+Q1. In this paper, using this method, we reconstruct the nilpotent BRST charges Q0 for the integer W2,s strings and the half-integer W2,s strings. Then we construct the exact grading BRST charge with spinor fields and give the new realizations of the half-integer W2,s strings for the cases of s = 3/2, 5/2, and 7/2.

5 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 کاملExplicit field realizations of W algebras
The fact that certain non-linear W2,s algebras can be linearized by the inclusion of a spin-1 current can provides a simple way to realize W2,s algebras from linear W1,2,s algebras. In this paper, we first construct the explicit field realizations of linear W1,2,s algebras with double scalar fields and spinor fields respectively. Then, after a basis inverting, the realizations of W2,s algebras ...
متن کاملfield 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 کاملHigher Spins from Nonlinear Realizations of OSp(1|8)
We construct a nonlinear realization of the supergroup OSp(1|8) which provides a minimal superconformal extension of N = 1, 4D supersymmetry with tensorial central charges. The coset supermanifold is OSp(1|8)/SL(4, R) , and it involves the tensorial superspace R(10|4) and Goldstone superfields defined on R(10|4). All Goldstone superfields can be covariantly expressed in terms of a single superf...
متن کاملHeisenberg algebra , anyons and d = 2 + 1 supersymmetry
A universal minimal spinor set of linear differential equations describing anyons and ordinary integer and half-integer spin fields is constructed with the help of deformed Heisenberg algebra with reflection. The construction is generalized to some d = 2 + 1 supersymmetric field systems. Quadratic and linear forms of action functionals are found for the universal minimal as well as for supersym...
