Quintessence, Supersymmetry and Inflation

Abstract

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.
