摘要：

Multiple initial state parton interactions in p(d)+A collisions are calculated in a Glauber-Eikonal formalism, which incorporates the competing pattern of low-p(T) suppression due geometrical shadowing, and a moderate-p(T) 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 pi(0) production at midrapidity show absence of dynamical shadowing in the RHIC energy range, roots similar to 20 - 200 GeV. Recent preliminary data at forward rapidity are addressed, and their interpretation discussed.
