The dilute A3 lattice model in regime 2 is in the universality class of the Ising model in a magnetic field. Here we establish directly the existence of an E8 structure in the dilute A3 model in this regime by expressing the 1-dimensional configuration sums in terms of fermionic sums which explicitly involve the E8 root system. In the thermodynamic limit, these polynomial identities yield a pro...

The exact perturbation approach is used to derive the (seven) elementary correlation lengths and related mass gaps of the two-dimensional dilute A4 lattice model in regime 2 − from the Bethe Ansatz solution. This model provides a realisation of the integrable φ(1,2) perturbation of the c = 7 10 conformal field theory, which is known to describe the off-critical thermal behaviour of the tricriti...

We study strangeness (K + , K − , and Λ) production and flow in Ni+Ni collisions at 1-2 AGeV, based on the relativistic transport model including the strangeness degrees of freedom. We find that strangeness spectra and flow are sensitive to the properties of strange hadrons in nuclear medium. The predictions of the chiral perturbation theory that the K + feels a weak repulsive potential and K −...

The hopping expansion of 8-vertex models in their Grassmann representation is studied. We use the functional similarity of the Ising model in this expansion with the hopping expansion of 2-D Wilson fermions to show that the lattice fermions are equivalent to the Self-avoiding Loop Model at bending rigidity 1/ √ 2. 1. Grasssmann representation for 8-vertex models and the hopping expansion Many l...
