Abstract

The multiplicity distribution of charged particles produced in the central rapidity region ($|\eta|<2.5$) is calculated within the multi-channel eikonal model using the AGK cutting rules and compared with ATLAS data at $\sqrt{s}=7$ and 13 TeV. The effects of color reconnection and/or string percolation are discussed.
