"The Shape of the Proton"
The proton is the smallest stable particle in nature whose radius has been measured. The same measurement methods, refined in recent years, in principle allow us to look inside this particle and to create a 3D image of the proton as a bound state of quarks and gluons. However, the complex interplay of quantum physics and the theory of relativity in the domain dominated by strong forces makes this view difficult. We will present recent progress toward successful “tomography” of the proton, achieved by combining theoretical methods from quantum field theory and neural networks. We will also address the general risks that arise when applying methods from one branch of science to problems in another.
Prof. Krešimir Kumerički, PhD
Krešimir Kumerički is a professor at the Department of Physics, Faculty of Science (PMF) in Zagreb, who did his PhD in Zagreb, and obtained further training in Oslo and Regensburg. He specializes in theoretical particle physics and studies processes that are observed or could potentially be observed in large accelerator facilities. His current research focus is on uncovering the three-dimensional structure of the proton and related particles, i.e., the way they are composed of quarks and gluons. In his work, he employs methods of quantum chromodynamics and was among the first to introduce machine learning techniques into these investigations.
