Reliability Analysis of the Results of the Known Experiments on Measuring of the Sachs Form Factor Ratio Using the Rosenbluth Technique. Polarization of the Final Proton in the ep⃗ → ep⃗ Elastic Process

A criterion for assessing the reliability of measurements of the Sachs form factor ratio using the Rosenbluth technique is proposed and applied to an analysis of three known experiments (Andivahis1994, Walker1994, Qattan2005) and a recent experiment on the CEBAF accelerator upgraded to 12 GeV at JLab (arXiv:2103.01842 [nucl-ex]). Based on the results of the JLab polarization experiments on measuring the ratio μ ₚG_E / μ ₚG_E G_M . -0em G_M in the e⃗p → ep⃗ process in the kinematics of the SANE Collaboration experiment (2020) on the measurement of double spin asymmetry in the e⃗p⃗ → ep process, numerical calculations are performed for the Q² dependence of polarization transferred to the proton in the ep⃗ → ep⃗ process when the initial proton at rest is partially polarized along the direction of motion of the detected recoil proton.
