Truncation of the operator product expansion for the (qq')-condensate components of the quark mass

# metadata.dc.description.abstract[].value
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
.
