In this talk, I will discuss the application of chiral interactions to few-baryon systems. Chiral interactions provide a systematic framework for describing baryonic interactions, including nucleon-nucleon (NN), hyperon-nucleon (YN), and hyperon-hyperon (YY) forces, as well as higher-order many-baryon interactions. After briefly introducing these interactions, I will present recent results for hypernuclei with mass numbers A=3 to A=8. Particular emphasis will be placed on the effects of charge-symmetry breaking on Lambda separation energies and the role of three-baryon interactions in shaping hypernuclear structure.

Biography

Andreas Nogga is a Senior Scientist at IAS-4, Forschungszentrum Jülich, Germany. He earned his Ph.D. in Physics in 2001 from Ruhr University Bochum, Germany, under the supervision of Prof. Dr. Walter Glöckle, focusing on nuclear and hypernuclear three- and four-body bound states.

His research career includes positions as a Research Associate at the University of Arizona (2001–2003), the Institute for Nuclear Theory at the University of Washington (2003–2004), and Forschungszentrum Jülich (2004–2007), where he has been a Scientific Staff member since 2007.

Dr. Nogga has been recognized with several visiting professorships, including the Peng Huanwu Visiting Professorship at ITP, CAS, Beijing (2019–2020) and the Robert and Rene Glidden Visiting Professorship at Ohio University, Athens, OH (2016–2017).
