How baryons decay and radiate in the highly-dense medium is probed experimentally in dilepton production rates from relativistic proton-proton and heavy-ion reactions. On the other hand, the microscopic structure of the nucleon and its excited states is revealed by electron scattering measurements. These methods appear unrelated. However they are connected since they explore the same physical systems with different space-like and time-like ranges of photon virtualities.
