| Abstract | |
The ratios of the baryon electric (G(E)) to magnetic (G(M)) form factors, G(E)/G(M), can provide us with important information on the structure of baryons in vacuum as demonstrated in recent studies for the proton and neutron systems. It has been argued that the corresponding in-medium ratios G(E)*/G(M)* can also provide useful information on the electromagnetic structure of baryons in a nuclear medium. Although the ratios may not be measured directly in experiments except for the proton at present, the double ratios (G(E)*/G(M)*)/(G(E)/G(M)) thorn can be directly related to the polarization-transfer measurements of bound baryons. In the present work we estimate, for the first time, the double ratios (G(E)*/G(M)*)/(G(E)/G(M)) for all the members of octet baryons in symmetric nuclear matter in the range Q(2) = 0-3 GeV2, where Q(2) = -q(2) with q being the four-momentum transfer.
