Implications of the $\rho(s)$ measurements by TOTEM at the LHC

Implications of the recent measurements of the parameter $\rho(s)$ (ratio of the real to imaginary parts of the forward scattering elastic amplitude) by TOTEM collaboration at $\sqrt{s}=13$ $TeV$ are discussed with emphasis on the rising energy dependence of the ratio of elastic to total cross--sections.Implications of the recent measurements of the parameter ρ(s) (ratio of the real to imaginary parts of the forward scattering elastic amplitude) by TOTEM collaboration at s = 13 TeV are discussed with emphasis on the rising energy dependence of the ratio of elastic to total cross-sections
