Query: First measurement of elastic, inelastic and total cross-section at
  $\sqrt{s}=13$ TeV by TOTEM and overview of cross-section data at LHC energies   The TOTEM collaboration has measured the proton-proton total cross section at
$\sqrt{s}=13$ TeV with a luminosity-independent method. Using dedicated
$\beta^{*}=90$ m beam optics, the Roman Pots were inserted very close to the
beam. The inelastic scattering rate has been measured by the T1 and T2
telescopes during the same LHC fill. After applying the optical theorem the
total proton-proton cross section is $\sigma_{\rm tot}=(110.6 \pm 3.4$) mb,
well in agreement with the extrapolation from lower energies. This method also
allows one to derive the luminosity-independent elastic and inelastic cross
sections: $\sigma_{\rm el} = (31.0 \pm 1.7)$ mb and $\sigma_{\rm inel} = (79.5
\pm 1.8)$ mb.
