  We show that in e-e+ colliders at energies above the Z-peak, the process e-e+
to b b(bar) becomes very sensitive to the presence of residual New Physics (NP)
effects described by the dim=6 SU(3)*SU(2)*U(1) gauge invariant operators
O(qW), O(qB) and O(bB). This observation should be combined with the already
known great sensitivity of the light fermion production through e-e+
annihilation above the Z-peak, to the bosonic operators O(DW) and O(DB). It is
important to emphasize that the effects of all these operators are largely
hidden at the Z-peak; while they are enhanced above it through the use the
"Z-peak subtracted representation". The observability limits for detecting
these operators at LEP2 and NLC, through such light fermion production
processes, are also established.
