Title: Nuclear dependence of single-hadron and dihadron production in {ital p}-{ital A} interactions at {radical}{ital s}=38.8 GeV

Abstract

We present a measurement of the W-to-Be per-nucleon cross-section ratio, {ital R}{sub W/Be}, for single hadrons and for opposite-sign hadron pairs produced in {ital p}-{ital A} collisions at {radical}{ital 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 {ital p}{sub {ital t}}, {ital m}, and {radical}{ital s}. Both the single-hadron and hadron-pair enhancements in {ital R}{sub W/Be} seen at intermediate values of {ital p}{sub {ital t}} and mass decrease with increasing {radical}{ital s}, consistent with a multiple-scattering model of parton scattering. {copyright} {ital 1996 The American Physical Society.}
