The AdS(4)/CFT3 duality is a new example of an integrable and exactly solvable AdS/CFT system. There is, however, a puzzling mismatch between the number of degrees of freedom used in the exact solution (4(B) + 4(F) scattering states) and 8(B) + 8(F) transverse oscillation modes of critical superstring theory. We off er a resolution of this puzzle by arguing that half of the string modes dissolve in the continuum of two-particle states once alpha' corrections are taken into account. We also check that the conjectured exact S-matrix of AdS(4)/CFT3  agrees with the tree-level worldsheet calculation.
