Phys. Rev. C 60, 027601 (1999) [4 pages]e+e- pairs from π-A reactions reexaminedReceived 19 January 1999; published 6 July 1999 We calculate dilepton production for the reactions π-C and π-Pb at 1.3 GeV within a semiclassical BUU transport model and compare our results to a previously published calculation. We show that a modified treatment of the ρ meson production and propagation gives substantially different results. We, furthermore, discuss uncertainties related to the electromagnetic decay of the ρ meson and the elementary π-N⃗e+e-X channels. © 1999 The American Physical Society URL:
