With the experimental data from STAR program on the centrality dependence of the p_T spectra of chargedhadron produced in d+Au collisions at (S_(NN))~(1/2)= 200 GeV,we show that there also exists a scaling distribution in thebackward rapidity regions.Using this scaling distribution,we get the theoretical psedorapidity asymmetry which isbasically in agreement with STAR data in the regions of 0≤|η|≤0.5 and 0.5≤|η|≤1.No theoretical models are usedin any part of this phenomenological analysis.
