Luminosity determination for the measurement of the total proton-proton cross section and the $\rho$-parameter with the ATLAS experiment at the LHC / Sanzani, Elisa (Universita e INFN, Bologna (IT)) ; Giacobbe, Benedetto (Universita e INFN, Bologna (IT)) ; Valentinetti, Sara (Universita e INFN, Bologna (IT)) ; Sbrizzi, Antonio (Universita e INFN, Bologna (IT))
The ATLAS experiment has measured the total proton-proton cross section during the LHC Run1 at $\sqrt s=7$ and $8~$TeV and in Run2 at $\sqrt s=13~$TeV using a luminosity dependent approach. [...]
