By using (pp) interactions at three different c.m. energies,$\left( {\sqrt 8 } \right)_{pp} $=30, 44, 62 GeV, it is shown that the average charged-particle multiplicity <nch>vs. the invariant mass of the hadronic systemm1,2 has the same behaviour as it hasvs. 2Ehad. Moreover, in both cases <nch> is shown to be nearly independent of$\left( {\sqrt 8 } \right)_{pp} $ and in good agreement with the average charged-particle multiplicity measured in the (e+e−) annihilation.

Charged Particle Multiplicities in ($p p$) Interactions and Comparison With ($e^+ e^-$) Data

By using three different c.m. energies in pp interactions,$\sqrt s $, 44, 62 GeV, it is shown that the average charged-particle multiplicity <nch> sclaes with$\sqrt s $ once the correct hadronic energy available for multiparticle production,Ehad, is used as basic parameter. The pp data, analysed in this way, are compared with e+e− data at equivalent energies. The agreement is very satisfactory.

Total cross-sections of protons, anti-protons, and pi and K mesons on hydrogen and deuterium in the momentum range 6-GeV/c to 22-GeV/c

The total cross sections σT of p, p¯, π±, and K± on hydrogen and deuterium have been measured between 6 and 22 GeVc at intervals of 2GeVc to an accuracy greater than previously reported. The method utilized was a conventional good-geometry transmission experiment with scintillation counters subtending various solid angles at targets of liquid H2 and D2. With the increase in statistical accuracy of the data, it was found that a previously adopted procedure of linearly extrapolating to zero solid angle the partial cross sections measured at finite solid angles was not a sufficiently accurate procedure from which to deduce σT. The particle-neutron cross sections are derived by applying the Glauber screening correction to the difference between the particle-deuteron and particle-proton cross sections. The cross sections σT(π+d) and σT(π−d) are equal at all measured momenta, which confirms the validity of charge symmetry up to 20GeVc. Results are presented showing the variation of cross sections with momentum; evidence is presented for a small but significant decrease in σT(pp) [and σT(pn)] in the momentum region above 12GeVc.

Total cross sections for π − , K − and p on protons and deutrons have been measured in the momentum range 15 to 60 GeV/ c . Total cross sections for particle interactions with neutrons have been determined with an energy dependent Glauber correction. Using the positive particle data obtained earlier with the same experimental apparatus, the differences of total cross sections for particles and antiparticles as well as for particles belonging to the same isospin multiplet have been calculated.
