    "abstract": "We analyze e+e- yields from matter containing baryons in addition to mesons\nusing a hydrodynamic approach to describe Pb+Au collisions at 158 A GeV/c. We\nuse two distinctly different e+e- production rates to provide contrast.\nAlthough the presence of baryons leads to significant enhancement of e+e-\nemission relative to that from mesons-only matter, the calculated results fall\nbelow the data in the range 400 \u003c M/MeV \u003c 600. The calculated results are,\nhowever, only 1.3-1.5 standard deviations below the data, which may not be\nstatistically significant.",
