We compute the anomalous dimension of the second moment of the transversity operator, (ψ) over bar sigma(munu)D(rho)psi, at three loops in both the (MS) over bar and RI' schemes. As a check on the result we also determine the O(1/N-f) critical exponent of the nth moment of the transversity operator in d dimensions in the large N-f expansion and determine leading order information on the n dependence of the anomalous dimension at three and four loops in (MS) over bar. In addition the RI' anomalous dimension of the non-singlet twist-2 operator, (ψ) over bar gamma(mu)D(nu)psi, is also determined. (C) 2003 Elsevier B.V. All rights reserved.
