Abstract
Properties of ρ -meson in symmetric nuclear matter are investigated within a light-front constituent quark model (LFCQM), using the in-medium input calculated by the quark-meson coupling (QMC) model. The LFCQM used here was previously applied in vacuum to calculate the ρ -meson electromagnetic properties, namely, charge G0 , magnetic G1 , and quadrupole G2 form factors, as well as the electromagnetic radius and decay constant. We predict the in-medium modifications of the ρ -meson electromagnetic form factors in symmetric nuclear matter.
