abstract

The multiplicity distribution of charged particles produced in the central rapidity ($|\eta|<2.5$) region is calculated for the eikonal and the $U$-matrix unitarization schemes using the AGK cutting rules and compared with the ATLAS 13 TeV data. The data favours the eikonal approach.

The U-matrix unitarization scheme forces a geometric, correlated pomeron distribution, while the eikonal scheme gives a Poisson distribution, changing predicted particle multiplicities.
