γ*N → N*(1520) transition form factors in light cone QCD sum rules.

The γ*N → N*(1520) reaction is studied in the framework of the light cone QCD sum rules method. The sum rules for the multipole form factors, namely, for the magnetic dipole GM(Q²), electric quadrupole GE(Q²), and Coulomb quadrupole GC(Q²) [i.e., form factors responsible for the γ*N → N*(1520) transition] are derived. Using these sum rules, the helicity amplitudes are presented as combinations of these multipole form factors, and their Q² dependences are studied. We compare our results on the helicity amplitudes with those of the spectator model predictions and with the existing experimental data. [ABSTRACT FROM AUTHOR]
