AbstractThe inclusive production of π± andK± mesons and of protons and antiprotons ine+e− annihilations has been measured at 34 GeV and 44 GeV center of mass energy; in addition π± mesons have been measured at 44 GeV c.m. energy. Differential cross sections and particle yields are given. At 34 GeV average multiplicities are:
$$\begin{gathered} \left\langle {n\left( {\pi ^ \pm } \right)} \right\rangle = 10.9 \pm 0.5,\left\langle {n\left( {K^ \pm } \right)} \right\rangle = 1.76 \pm 0.20, \hfill \\ \left\langle {n\left( {p + \bar p} \right)} \right\rangle = 0.67 \pm 0.06 \hfill \\ \end{gathered} $$
and at 44 GeV:
$$\left\langle {n\left( {\pi ^ \pm } \right)} \right\rangle = 11.1 \pm 0.5,\left\langle {n\left( {\pi ^0 } \right)} \right\rangle = 5.4 \pm 1.0.$$
