%0 Journal Article %T Similarity Renormalization Group Evolution of Three-Nucleon Forces in a Hyperspherical Momentum Representation %A Kyle A. Wendt %J Physics %D 2013 %I arXiv %R 10.1103/PhysRevC.87.061001 %X A new framework for computing the Similarity Renormalization Group (SRG) evolution of three-nucleon forces (3NF) in momentum representation is presented. The use of antisymmetric three-particle hyperspherical momentum states ensures unitary evolutions within certain basis truncations, much like antisymmetric harmonic oscillator SRG evolutions. Additionally, in each partial wave the $T_{\mbox{rel}}$-SRG regulator is exactly represented, similar to recent 3NF momentum representation evolutions. Unitary equivalence is demonstrated for the triton using several chiral two- plus three-nucleon interactions. This method allows for a clean visualization of the evolution of the three-nucleon forces, which manifests the SRG decoupling pattern and low-momentum universality. %U http://arxiv.org/abs/1304.1431v1
