Scaling in the charged-particle multiplicity distributions at the ISR and comparison with (e+e-) data

  • Published:
Lettere al Nuovo Cimento (1971-1985)

Summary

The distribution of the charged-particle multiplicities at the ISR are studied in terms of the effective energy available for particle production in (pp) interactions. These distributions are found to scale once the effective energy, obtained via the leading subtraction method, is used. A comparison with the charged particle distributions measured in (e+e-) annihilation shows a clear difference. This could be interpreted in terms of gluon-induced and quark-induced jets; where the gluoninduced jets are characterized by a wider multiplicity distribution with respect to quarkinduced jets.
