Abstract

We present a measurement of the W-to-Be per-nucleon cross-section ratio, RW/Be, for single hadrons and for opposite-sign hadron pairs produced in p-A collisions at √s=38.8 GeV. The data fill in regions of intermediate transverse momentum and dihadron mass that previously have revealed cross-section enhancements for scattering from nuclear targets. When combined with previous measurements, the new results help delineate the dependence of nuclear effects on the kinematic variables pt, m, and √s. Both the single-hadron and hadron-pair enhancements in RW/Be seen at intermediate values of pt and mass decrease with increasing √s, consistent with a multiple-scattering model of parton scattering.
