Abstract The first double diffractive cross-section measurement in the very forward region has been carriedout by the TOTEM experiment at the LHC with center-of-mass energy of √s = 7 TeV. By utilizingthe very forward TOTEM tracking detectors T1 and T2, which extend up to pseudo rapidity |$\eta$|=6.5, a clean sample of double diffractive pp events was extracted. From these events, we measured the cross-section $\sigma_{DD}$ = (116±25) mb for events where both diffractive systems have 4.7 < |$\eta$|$_{min}$ < 6.5.
