Boost Invariance and Multiplicity Dependence of the Charge Balance Functionin ${\pi }^{+}p$ and $K^{+}p$ Collisions at $\sqrt{s}=22$ GeV/c

Abstract

Boost invariance and multiplicity dependence of the charge balance function are studied in $π^{+}\rp$ and $\rK^{+}\rp$ collisions at 250 GeV/$c$ incident beam momentum. Charge balance, as well as charge fluctuations, are found to be boost invariant over the whole rapidity region, but both depend on the size of the rapidity window. It is also found that the balance function becomes narrower with increasing multiplicity, consistent with the narrowing of the balance function when centrality and/or system size increase, as observed in current relativistic heavy ion experiments.
