We present consistent theoretical descriptions of the πN→e+e−N
and γN→e+e−N reactions on proton and neutron targets for total
center of mass energies s ranging between 1.50 GeV and 1.75 GeV. These
reactions are complementary to study the coupling of low-lying baryon
resonances to vector meson-nucleon channels. We show in particular how the
resonant structure of the amplitudes for both processes generates specific and
large quantum interferences between ρ- and ω-meson decays into
e+e− pairs. Data on the πN→e+e−N and γN→e+e−N
reactions are expected in the near future from the HADES program at GSI and
from dilepton studies with CLAS at JLab.Comment: 6 pages, 6 figures, Paper presented at Hirschegg 2004, 'Probing
