    Abstract:

    We present the calculations of isospin splitting mass of pions and nucleons in the Sakai- Sugimoto model of holographic QCD. We find that mπ± − mπ0 ≃ 1.8 MeV and the electromagnetic mass difference of nucleons, (Mp − Mn)QED = 0.48 MeV, taking the Kaluza-Klein scale, MKK = 949 MeV.
