摘要：

The conformal partial wave analysis of four-point functions of 1/2-BPS operators belonging to the SU(4) [0,p, 0] representation is undertaken for p = 2,3,.4. Using the results of N = 4 superconformal Ward identities the contributions from protected short and semi-short multiplets are identified in terms of the free-field theory. In the large N limit., contributions corresponding to long multiplets with twist up to 2p - 2 are absent. The anomalous dimensions for twist two singlet multiplets are found to order g(4) and agree with other perturbative calculations. Results for twist four and six are also found.
