Abstract

Based on the behavior of elastic scattering of proton and anti-proton at \(\sqrt{s}=1.96\) TeV for squared four-momentum transfer \(0.26<{-}t<1.2(\)GeV\(/c)^{2}\), form factor of proton is predicted. Simplest version of Chou–Yang model is employed for extracting this form factor by fitting experimental data of differential cross section from D0 experiment to a single Gaussian. Root mean square (rms) matter radius of proton is calculated using this form factor. It is found to be equal to 0.89 fm. Which is in good agreement with experimental data and theoretically predicted values from other models.
