The basis for fermion and boson twist-3 operators in quantum chromodynamics is constructed for deep inelastic scattering of electrons by a polarized target. In the calculations of the matrix elements for the operators, the quarks and gluons can be considered to lie on the mass shell, so that the helicity-amplitude technique can be used. A theoretical description of the process within the framework of the parton model calls for introducing a correlation density matrix expressed in terms of the product of wave functions with different numbers of partons. Evolution equations for the correlation density matrix are derived in the nonsinglet and singlet cases. The anomalous-dimensionalities matrix is found and its rank is shown to increase with the angular-momentum number.
