Abstract: | Assuming the validity of the universal multiplicity hypothesis of quantum chromodynamics, we estimate bounds on quark gluon coupling (αS) and quark mass (m) from the experimental data on charged hadron multiplicities. We obtain 0.3 < αS < 0.5 and m ≈ 100 MeV. Our analysis also suggests the universal quark confinement region to be ≈ O (mπ?1). Comparison with experiment is made for both the hadronic and leptonic induced reactions. |
