It is shown that this sensitivity is comparable to that encountered in ultrarelativistic heavy-ion collisions. It is also shown how a significant broadening of the mesons affects other photonuclear processes.Talk at Hirschegg 2000: Hadrons In Dense MatterNuclear TheoryHigh Energy Physics - Phenomenologytext
