In this work, the properties of the rho meson at rest in cold symmetric nuclear matter are studied. We make use of a chiral unitary approach to pion-pion scattering in the vector-isovector channel, calculated from the lowest-order Chiral Perturbation Theory (chiPT) Lagrangian including explicit resonance fields. Low-energy chiral constraints are considered by matching our expressions to those of one-loop chiPT. To account for the medium corrections, the rho couples to pipi pairs which are properly renormalized in the nuclear medium, accounting for both p-h and Delta-h excitations. The terms where the rho couples directly to the hadrons in the p-h or Delta-h excitations are also accounted for. In addition, the rho is also allowed to couple to N*(1520)-h components.
