Description

We report on measurements of event-by-event charge fluctuations in π+p and K+p collisions at 250 GeV/c. The dependence of these fluctuations on the size of the rapidity windows are presented for the first time in the full phase-space domain. The corrections for the influence of global charge conservation and leading-particle stopping are tested by the data. The discrepancy due to incomplete correction given by STAR and PHENIX are estimated. The dependence of the fluctuations on the position of the rapidity bin and on the multiplicity at different rapidity windows are also presented
