A self-consistent renormalization (RG) scheme has been applied to nonhelica
l magnetohydrodynamic turbulence with normalized cross helicity sigma (c) =
0 and sigma (c) --> 1. Kolmogorov's 5/3 power law is assumed in order to c
ompute the renormalized parameters. It has been shown that the RG fixed poi
nt is stable for d greater than or equal to d(c) approximate to 2.2. The re
normalized viscosity nu* and resistivity eta* have been calculated, and the
y are found to be positive for all parameter regimes. For sigma (c) = 0 and
large Alfven ratio (ratio of kinetic and magnetic energies) r(A), nu* = 0.
36, and eta* = 0.85. As r(A) is decreased, nu* increases and eta* decreases
, until r(A) approximate to 0.25, where both nu* and eta* are approximately
zero. For large d, both nu* and eta* vary as d(-1/2). The renormalized par
ameters for the case sigma (c) --> 1 are also reported. (C) 2001 American I
