We study excited spherical branes (``giant gravitons'') in AdS × S spacetimes with background flux. For large excitation, these branes may be treated semiclassically. We compute their spectra using Bohr-Sommerfeld quantization and use the AdS/CFT correspondence to relate them to anomalous dimensions in the dual field theory at strong coupling, expressed as a series expansion in powers of 1/N. These effects resemble those due to k-body forces between quarks in Hartree-Fock models of baryons at large N. For branes expanded in AdS, we argue that the anomalous dimensions are due to loop corrections to the effective action.
