The pseudorapidity distribution in minimum-bias d + Au collisions of charged particles at √SNN = 200 GeV, was investigated. The probability of this distribution to fall rapidly was less in gold direction as compared to deuteron direction. The estimates of total charged particle production were also described, which were based on extrapolations outside the measured pseudorapidity region. The results show that final-sate interactions (FSI) and popcorn mechanism, broadens the gold side peak, which leads to moderate increase of particle multiplicity in region η≤-3.5.
