Model-Independent Femtoscopic Lévy Imaging for Elastic Proton-Proton Scattering

Research output: Contribution to journalArticle


A model independent Lévy expansion method is introduced to describe nearly Lévy shaped squared moduli of Fourier transforms. We apply this method to precisely characterize the most recent elastic scattering data of proton-proton collisions at $$\sqrt s = 13$$ TeV. The results reveal a substructure of protons, which is found to be significantly larger and darker in high energy proton-proton collisions at the TeV scale, as compared to a rather faint and apparently overlooked substructure, that we also identify in elastic proton-proton scattering at the ISR energy range of $$\sqrt s = 23{\kern 1pt} - {\kern 1pt} 62$$ GeV.
