The TOTEM collaboration has measured for the first time the proton-proton total cross section at energy of 8 TeV using a luminosity-independent method based on the application of the optical theorem. The measurements of the total nuclear elastic rate Nel and of the total inelastic rate Ninel have given the following values for the total cross section, integrated elastic and inelastic cross sections: σtot=(101.7±2.9) mb, σel =(27.1 ± 1.4) mb and σinel =(74.7±1.7) mb.
