Supersymmetric (SUSY) models and dynamical breaking of symmetries have been
used to explain hierarchies of mass scales. We find that a chiral
representation, $bar{bf 10}, oplus, bar{bf 5}, oplus, 2cdot {bf 5}$
in SUSY SU(5) in the hidden sector, breaks global SUSY dynamically, by
producing a composite field $phi$ below the SU(5) confinement scale. Starting
with this dynamincally generated scale, we attempt to explain two vastly
different mass scales in two standard models of physics, one in particle
physics and the other in cosmology. Gavitational effects transmit this
dynamical breaking to the SM superpartners and the quintessential vacuum
energy. The SM superpartners feel the effects just by the magnitude of the
gravitino mass while the smallness of the quintessential vacuum energy is due
to the composite nature of $phi$. The composite $phi$ has a global symmetry
which is hardly broken in SUSY and hence its phase can be used toward a
quintessential axion for dark energy of the Universe.
