Central production in ALICE in proton-proton collisions at the LHC — •Rainer Schicker for the ALICE collaboration — Phys. Inst., Heidelberg

Central production in proton-proton collisions has been analysed from the low energy range √s = 12.7-63 GeV of the ISR at CERN up to the presently highest energy available of √s = 13 TeV achieved in Run II at the LHC. Central production is characterized by the hadronic state produced at or close to midrapidity, and by the two forward scattered protons, or remnants thereof. No particles are produced between the midrapidity system and the beam particles or remnants on either side of the central system, thereby resulting in a double gap topology of the event. I will give an overview of the ongoing efforts in the ALICE collaboration to analyse double gap events taken in Run II at the LHC, and present the prospects of such data taking in Run III.
