Abstract:
|
Quark-condensate contributions to
m
dyn
, the quark mass generated by the dynamical breakdown of chiral symmetry, are shown to arise from only the first two terms of the operator-product expansion (OPE) for the appropriate
O
(
g
2
)
nonperturbative vacuum expectation value. Since the
m
|
p
|
expansion parameter of the OPE is unity on the gauge-invariant
p
=
m
dyn
propagator pole, such truncation of OPE contributions is an essential support to the calculation of
m
dyn
