A-dependence of weak nuclear structure functions

الأصل · EN

Effect of nuclear medium on the weak structure functions F₂ᵃ(x,Q²) and F₃ᵃ(x,Q²) have been studied using charged current (anti)neutrino deep inelastic scattering on various nuclear targets. Relativistic nuclear spectral function which incorporate Fermi motion, binding and nucleon correlations are used for the calculations. We also consider the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. Using these structure functions, Fᵢᵃ/Fᵢproton and Fᵢᵃ/Fᵢdeuteron(i=2,3, A=¹²C, ¹⁶O, CH and H₂O) are obtained.
