The Similarity Renormalization Group for Three-Body Bound State; A Three-Dimensional Approach

ORAL

Abstract

Similarity renormalization group (SRG) evolution of two- and three-body interactions is studied in a three-dimensional (3D) momentum representation. The SRG flow equations are formulated as a function of momentum vector variables, without using the partial wave (PW) representation. The non-PW form of SRG evolved two- and three-body interactions, obtained from spin-independent interactions, are used to solve the Faddeev integral equations for the bound state in 3D. The dependence of the binding energy on the flow parameter of the evolved two-and three-body interactions is investigated and properties of wave function are studied as function of the SRG evolution.
