Nuclear-medium effects in the weak structure functions $F_2(x,Q^2)$ and
$F_3(x,Q^2)$ in the 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 also consider the pion and rho meson cloud contributions calculated from a
microscopic model for meson-nucleus self-energies. Using these structure
functions, the results for the differential cross section have been obtained
and compared with the CERN Hybrid Oscillation Research apparatUS (CHORUS) data.
The results for the ratios $\frac{2F_{i}^{Pb}}{208F_i^D}$,
$\frac{4F_{i}^{Pb}}{208F_i^{He}}$, $\frac{12F_{i}^{Pb}}{208F_i^C}$,
$\frac{16F_{i}^{Pb}}{208F_i^O}$, and $\frac{56F_{i}^{Pb}}{208F_i^{Fe}}$ (i=2,3)
have also been obtained and a few have been compared with some of the
phenomenological fits.
