Exploring time like tranistions in pp, πp and AA reactions with HADES

Radiative transition of an excited baryon to a nucleon with emission of a virtual massive photon converting to dielectron pair (Dalitz decays) provides important information about baryon-photon coupling at low q 2 in timelike region. A prominent enhancement in the respective electromagnetic transition Form Factors (etFF) at q 2 near vector mesons ρ/ω poles has been predicted by various calculations reflecting strong baryon-vector meson...
