Abstract
Multiple initial state parton interactions in p(d)+A collisions are calculated in a Glauber-Eikonal formalism, which incorporates the competing pattern of low-pT suppression due geometrical shadowing, and a moderate-pT Cronin enhancement of hadron spectra. Dynamical shadowing effects, which are not included in the computation, may be extracted by comparing experimental data to the baseline provided by the Glauber-Eikonal model. Data for neutral pion production at midrapidity show absence of dynamical shadowing in the RHIC energy range, sqrt(s)~20-200 GeV. Recent preliminary data at forward rapidity are addressed, and their interpretation discussed.
