Totem: on the Parameter ρ at 13 TeV

The results on elastic proton-proton scattering that were obtained by the TOTEM Collaboration at the LHC (Large Hadron Collider) energy of 13 TeV are analyzed. It is shown that the statistical significance of these results is questionable in some respects. Specific examples show that the parameter rho extracted from experimental data is model-dependent.
