    "abstract": "We examine entropy production in relativistic U+U collisions on the basis of\na Color Glass Condensate (CGC) type picture as implemented in the\nKharzeev-Levin-Nardi model (KLN). In this framework, we find that the peak\nentropy density produced in tip-on-tip U+U collisions is about 30% greater than\nthat seen in central Au+Au collisions. Although the resulting difference in the\nproduced charged particle multiplicity between tip-on-tip and side-on-side\ncollisions is smaller than that predicted by previous Glauber model estimates,\nit is still large enough to allow for experimental discrimination between\naverage orientations of the uranium nuclei. We also point out that in the\nsaturation/CGC approach the collision geometry plays a more important role than\npreviously believed, and that the observed centrality dependence of the\nproduced particle multiplicity per participant in Au+Au collisions can be\nqualitatively reproduced even without running coupling effects.",
