N2 - We report Cu+Cu root s(NN) = 200 GeV strange baryon and meson yields which reveal that collision geometry plays a crucial role for particle production. Relative to Au+Au collisions with similar numbers of participating nucleons, <N-part >, at the same energy, central Cu+Cu collisions exhibit higher mid-rapidity integrated yields per <N-part > for the Lambda, (Lambda) over bar, K-S(0) particles. In addition, higher mid-p(T) Lambda/K-S(0) ratios are observed in Cu+Cu for the overlapping <N-part > range.
