• Electromagnetic mass difference of hadron is discussed on the basis of the SU(3) bootstrap model in which electromagnetic mass difference of hadron comes from the electromagnetic mass differences of bound hadrons, Coulomb interaction and magnetic interaction between bound hadrons. Low-lying states are assumed to be main ingredients of hadron, for instance: Baryon octet (B_8) is bound states of baryon octet and pseudoscalar meson octet (P_8) and those of baryon decuplet (B_<10>) and pseudoscalar meson octet. We can represent this in a simple way, B_8=(B_8, P_8)+(B_<10>, P_8). In a similar fashion we have also B_<10>=(B_<10>, P_8)+(B_8, P_8), P_8=(P_8, V_8)+(V_8, V_8)+(B_8, B^^-_8), and V_8=(P_8, P_8)+(P_8, V_8)+(B_8, B^^-_8). Then we find that the p-n mass difference is caused mainly by the electromagnetic mass differences of baryon decuplet. From our qualitative analysis of the electromagnetic mass difference of vector meson in the SU(3) bootstrap model, we also find that vector mesons tend to dissociate into two pseudoscalar mesons (P state) with dominant probability, namely that Chew's π-π resonance model of ρ meson is the most preferable.
