Forward distributions of identified charged particles and net charge and strangeness distributions in $K^{+}p$ interactions at 70 GeV/c

Presents preliminary results from 70 GeV/c K^{+}p interactions in BEBC filled with hydrogen, using the External Particle Identifier (EPI) to yield a separation of\pi^{+} and K^{+} mesons in the forward region. The single charged particle (\pi^{+},\pi^{-}, K^{+}) longitudinal distributions are studied and compared to the quark counting rules. The (\pi^{+}/\pi^{-}) ratio is given for the K^{+} fragmentation region. From linear combinations of the x /sub F/ distributions, the charged pion fragmentation functions are extracted. A comparison of the net charge and net strangeness distributions of the beam fragments as function of the c.m. rapidity y, gives an estimate of the charge and strangeness correlation lengths.
