Abstract: Nuclear-medium effects on the weak structure functions ${F}_{2}(x,{Q}^{2})$ and ${F}_{3}(x,{Q}^{2})$ in charged-current neutrino and antineutrino induced deep-inelastic reactions in ${}^{208}$Pb have been studied. The calculations have been performed in a theoretical model using relativistic nuclear spectral functions which incorporate Fermi motion, binding, and nucleon correlations. We have also included the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. Using these structure functions, differential scattering cross sections have been obtained and compared with the CERN Hybrid Oscillation Research Apparatus (CHORUS) data. The results for the ratios $\frac{2{F}_{i}^{Pb}}{208{F}_{i}^{D}}$, $\frac{4{F}_{i}^{Pb}}{208{F}_{i}^{He}}$, $\frac{12{F}_{i}^{Pb}}{208{F}_{i}^{C}}$, $\frac{16{F}_{i}^{Pb}}{208{F}_{i}^{O}}$, and $\frac{56{F}_{i}^{Pb}}{208{F}_{i}^{Fe}}$ ($i=2,3$) have also been obtained and compared with some of the phenomenological fits.
