Forward hadronic scattering at 7 TeV: predictions for the LHC; an update

Abstract

The LHC has successfully run for a long period at half energy, 7 TeV. In this note, we update earlier full-energy Large Hadron Collider (LHC) forward hadronic scattering predictions \cite{physicsreports}, giving new predictions, including errors, for the $pp$ total and inelastic cross sections, the $\rho$-value, the nuclear slope parameter $B$, $d\sigma_{\rm el}/dt$, and the large gap survival probability at the current 7 TeV energy.
