Abstract

We calculate the rapidity distribution and the total cross section of coherent and incoherent ρ production in heavy ion ultraperipheral collisions at √sNN= 130 GeV using the generalized vector dominance model and the Gribov-Glauber approach. We find the coherent cross section of ρ-production σcoh = 490 mb compared to σcoh = 310 ± 170 ± 80 mb recently reported by the STAR collaboration at RHIC. The predicted cross section inside the acceptance of the experiment, |y| ≤ 1, agrees with the data within half a standard deviation. It is emphasized that measurements of the rapidity distribution will provide a much more stringent test of the used approach.
