Central diffractive meson production in p+p collisions at √(s)=7 TeV at the ALICE experiment

The ALICE experiment is one of the four large experiments at the LHC. ALICE collected proton-proton collision data at √(s)=7 TeV from 30 March to 4 November 2010. In this contribution, our first analysis results of central diffractive meson production with a signature of pseudo-rapidity gaps in the forward regions are presented. The measurement reconstructs the invariant mass spectrum from events with two pions in the central barrel, and the pseudo-rapidity gap is identified as null activity in the forward detectors. With current statistics, an enhancement of f0(980) and f2(1270) in double-gap events is seen.
