The Institute of Nuclear and Particle Physics (INPP) presents Andreas Nogga, of Forschungszentrum Jülich and Glidden Professor, Ohio University, presenting “Predictions for Light Hypernuclei based on chiral and similarity renormalization group-evolved interactions,” on Tuesday, October 25, at at 4 p.m. in Edwards Accelerator Lab, Roger W. Finlay Conference Room.

Abstract: Chiral perturbation theory is a useful tool to develop consistent two-and more-baryon interactions based on the symmetries of Quantum Chromo Dynamics. In this talk, I will discuss predictions for the binding energies of the light hypernuclei 3-Lambda-H, 4-Lambda-He and 4-Lambda-H based on chiral hyperon-nucleon interactions in leading and next-to-leading order. For the application to larger systems, it is necessary to evolve such interactions using the similarity renormalization group. After a brief introduction to this method, I will use binding energies of light hypernuclei to quantify the contribution of three-baryon interactions induced by this technique.
