FORM FACTORS AND CORRELATION FUNCTIONS OF THE STRESS-ENERGY TENSOR IN MASSIVE DEFORMATION OF THE MINIMAL MODELS (En)1⊗ (En)1/(En)2

Abstract: The magnetic deformation of the Ising Model, the thermal deformations of both the Tricritical Ising Model and the Tricritical Potts Model are governed by an algebraic structure based on the Dynkin diagram associated to the exceptional algebras E n (respectively for n = 8, 7, 6). We make use of these underlying structures as well as of the discrete symmetries of the models to compute the matrix elements of the stress-energy tensor and its two-point correlation function by means of the spectral representation me… Show more

“…However, the convergence property of the truncated series is much better [8] and as a matter of fact it neatly approximates the correlator up to the region r ∼ ξ, as has been checked in several examples (see, for instance [10,11,14,45,46,47]). Therefore the truncated spectral series is assumed to estimate the integral I 2 (R) in eq.…”

“…(see [28] where this property is exploited for the computation of the matrix elements of the energy-momentum tensor as well as of its two-point correlation function). The tricritical Ising model is also the simplest example of superconformal field theory [29]: its Hilbert space contains a finite number of irreducible representations of the super-Virasoro algebra (the antiholomorphic part is omitted)…”
