Abstract
We calculate dilepton production for the reactions pi(-)C and pi(-)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 t he rho meson production and propagation gives substantially different resul ts. We, furthermore, discuss uncertainties related to the electromagnetic d ecay of the rho meson and the elementary pi(-)N-->e(+)e(-)X channels. [S055 6-2813(99)02008-7].
