Measurement of dielectron production in central Pb-Pb collisions at √sNN=2.76 TeV
(American Physical Society, 2019-02-14)
The first measurement of dielectron (e+e−) production in central (0–10%) Pb–Pb collisions at √sNN=2.76TeV at the LHC is presented. The dielectron invariant-mass spectrum is compared to the expected contributions from hadron ...
