Quintessence, supersymmetry and inflation

Recent data point in the direction of a Lambda dominated universe. We brief ly review "Quintessence" as a model for a dynamical cosmological term and a nalyse the role of Susy QCD as a possible particle physics candidate. The m ultiscalar content of the theory is fully taken into account and interactio n with other cosmological fields is discussed. Finally, the possibility of constructing a unified scheme for quintessence and inflation is mentioned.
