    "abstract": "The heavy ion cross section for continuum e+ e- pair production has been\ncalculated to all orders in Z alpha. Comparison is made with available CERN SPS\nand RHIC STAR data. Computed cross sections are found to be reduced from\nperturbation theory with increasing charge of the colliding heavy ions and for\nall energy and momentum regions investigated. Au or Pb total cross sections are\nreduced by 28% (SPS), 17% (RHIC),and 11% (LHC). For very high energy (E_e+,\nE_e- \u003e 3 GeV) forward pairs at LHC the reduction from perturbation theory is a\nbit larger (17%). Use of zero degree calorimeter triggering (and thus small\nimpact parameter weighting) makes impact parameter representation of exact pair\nproduction useful. Preliminary exact calculations in the zero impact parameter\nlimit show a much larger reduction from perturbation theory (about 40%) at both\nRHIC and LHC.",
