The current status of constituent quarks in resonance photo and electroproduction
The author illustrates the current status of quark models and approaches based on the Melosh transformation by concentrating on the D/sub 13/(1520), a resonance with well determined couplings. A real photon with J/sub z/=+1 is considered to interact with a nucleon with J/sub Z/=+or-1/2 to form the r...

| Sumario: | The author illustrates the current status of quark models and approaches based on the Melosh transformation by concentrating on the D/sub 13/(1520), a resonance with well determined couplings. A real photon with J/sub z/=+1 is considered to interact with a nucleon with J/sub Z/=+or-1/2 to form the resonant state in either J/sub Z/=+1/2 or +3/2. (9 refs). |
