چکیده
We show that any covariant scattering amplitude of the W 3 string will contain, as part of its integrand, a factor that obeys the differential equations satisfied by an Ising model correlation function. This factor can thus be identified with such a correlation function, in agreement with a previous result of the authors. The W 3 string is also shown to contain an N = 2 parafermion theory, and hence to contain in addition the non-linear infinite-dimensional W-algebra corresponding to this parafermion theory. The physical states form a representation of this algebra.

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...

A relation between the Z3-graded Grassmann variables and parafermions is established. Coherent states are constructed as a direct consequence of such a relationship. We also give the analog of the Bargmann-Fock representation in terms of these Grassmann variables.

We systematically study the exclusion statistics for quasi-particles for Conformal Field Theory spectra by employing a method based on recursion relations for truncated spectra. Our examples include generalized fermions in cCFT < 1 unitary minimal models, Zk parafermions, and spinons for the su(n)1, so(n)1 and sp(2n)1 Wess-Zumino-Witten models. For some of the latter examples we present explici...

We show that deformed Heisenberg algebra with reflection emerging in parabosonic constructions is also related to parafermions. This universality is discussed in different algebraic aspects and is employed for the description of spin-j fields, anyons and supersymmetry in 2+1 dimensions.

A new parafermionic algebra associated with the homogeneous space A (2) 2 /U(1) and its corresponding Z-algebra have been recently proposed. In this paper, we give a free boson representation of the A (2) 2 parafermion algebra in terms of seven free fields. Free field realizations of the parafermionic energy-momentum tensor and screening currents are also obtained. A new algebraic structure is ...
