Luminosity-Independent Measurement of the Proton-Proton Total Cross Section at $\sqrt{s}$ = 8 TeV
TOTEM has measured the proton-proton total cross-section at $\sqrt{s}$ = 8 TeV using a luminosity independent method. In LHC fills with dedicated beam optics, the Roman Pots have been inserted very close to the beam allowing the detection of 90% of the nuclear elastic scattering events. Simultaneou...

| description | TOTEM has measured the proton-proton total cross-section at $\sqrt{s}$ = 8 TeV using a luminosity independent method. In LHC fills with dedicated beam optics, the Roman Pots have been inserted very close to the beam allowing the detection of 90% of the nuclear elastic scattering events. Simultaneously the inelastic scattering rate has been measured by the T1 and T2 Telescopes. By applying the optical theorem, the total proton-proton cross-section of (101.7 $\pm$ 2.9)mb is determined, well in agreement with the extrapolation from lower energies. This method allows also to derive the luminosity-independent elastic and inelastic cross-sections: $\sigma_{el}$ = (27.1 $\pm$ 1.4)mb; $\sigma_{inel}$ = (74.7 $\pm$ 1.7)mb. |
