Abstract
We present a measurement of the atomic mass dependence of central Xi(- ) and Xi(+) production. It is measured using a sample of 22 459 Xi(-)' s and Xi(+)'s produced in collisions between a 250 GeV pi(-) beam and targets of beryllium, aluminum, copper, and tungsten. The relative cro ss sections are fit to the two parameter function sigma(0)A(alpha), wh ere A is the atomic mass. We measure alpha= 0.924+/-0.020+/-0.025, for Feynman x in the range -0.09<x(F)<0.15.
