Abstract
We present STAR's measurement of the e+eâ continuum as a function of centrality, invariant mass, and transverse momentum for U+U collisions at sNN=193Â GeV. Also reported are the acceptance-corrected e+eâ invariant mass spectra for minimum-bias Au+Au collisions at sNN=27,39, and 62.4 GeV and U+U collisions at sNN=193Â GeV. The connection between the integrated e+eâ excess yields normalized by charge particle multiplicity (dNch/dy) at mid-rapidity and the lifetime of the fireball is discussed.
