The Shape of the Proton
(Krešimir Kumerički - Department of Physics, PMF, Zagreb)

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 machine learning.
