Reduction of the proton radius discrepancy by 3σ

We show that in previous analyses of electron–proton scattering, the uncertainties in the statistical procedure to extract the proton charge radius are underestimated. Using a fit function based on a conformal mapping, we can describe the scattering data with high precision and extract a radius valu...
