Description
Abstract:
Baryons are the most fundamental three-body systems in Nature, investigating the structure of baryons is a significant challenge in modern physics. The continuum Schwinger function methods (CSMs), when utilized judiciously, can provide meaningful predictions for the study of baryons, including their properties at nonzero temperature and chemical potential. In this talk, I will present the unified computation of axial-vector and pseudoscalar form factors related to the nucleon, the ∆-baryon, and the transition processes between them. I will also discuss the screening masses of positive- and negative-parity hadron ground-states, including those with strangeness.
About the speaker:
Chen Chen (陈晨) received his Ph.D. from the University of Science and Technology of China between 2007 and 2013, with a period of joint training as a graduate student at Argonne National Laboratory in the United States from 2011 to 2013. After completing his doctoral studies, Chen continued his research at USTC as a postdoctoral fellow until 2016. From 2016 to 2019, he pursued further postdoctoral research at São Paulo State University in Brazil under the FAPSPE Fellowship. This was followed by a postdoctoral position at Justus Liebig University Giessen in Germany from 2019 to 2021. He Joined USTC in 2022.
Dr. Chen's primary research focus lies in continuum Schwinger function methods for quantum field theory, particularly their application in predicting phenomena related to strong interactions within the Standard Model of particle physics. His work has made significant contributions to the understanding of hadron structure and dynamics. His current research interests include: (1). Baryon structure within the quark+diquark framework; (2). Advancing Dyson-Schwinger equations beyond the rainbow-ladder truncation; (3). Theoretical investigations into exotic hadrons.
