Abstract
Using the formal analogy between the Dick superstring inspired
model and
the problem of the building of an
Eguchi-Hanson metric in 4D N = 2 harmonic
superspace (HS),
we derive a general formula for the quark-quark interaction
potential
V(r) including
the Dick confining potential. The interquark potential V(r) depends
on the
dilaton-gluon coupling and may be related to the parameterization
of confinement by
the quark and gluon vacuum condensates. It is also shown how
the axion field may be
incorporated in agreement with 10D type IIB superstring requirements.
Others features
are also discussed.
