The similarity renormalization group procedure formulated in terms of effective particles is briefly reviewed in a series of selected examples that range from the model matrix estimates of its numerical accuracy to issues of the Poincaré symmetry in constituent theories to derivation of the Schrödinger equation for quarkonia in QCD.

We derive a boundary action of N = 2 super-Liouville theory which preserves both N = 2 supersymmetry and conformal symmetry by imposing explicitly T = T and G = G. The resulting boundary action shows a new duality symmetry.

We perform a detail analysis of two models for neutrino π+ production via ∆++ excitation and conclude that Marteau model [1] althrough based on simplified dynamical assumptions leads to similar results as well established model based on modelling of nucleon-Delta transition current with several form-factors [2].
