  Recent data point in the direction of a $\Lambda$ dominated universe. We
briefly review ``Quintessence'' as a model for a dynamical cosmological term
and analyse the role of Susy QCD as a possible particle physics candidate. The
multiscalar content of the theory is fully taken into account and interaction
with other cosmological fields is discussed. Finally, the possibility of
constructing a unified scheme for quintessence and inflation is mentioned.
