SOFT SUSY MASSES AND THE DYNAMICAL DETERMINATION OF THE GRAVITINO MASS

We discuss in detail the possibility of determining dynamically the gr avitino mass m(3/2), which is related to the supersymmetry breaking sc ale, within the minimal supersymmetric standard model (MSSM). Using th e complete MSSM spectrum, we minimize the vacuum energy including one- loop corrections and a cosmological term of O(m(3/2)(4)) induced by th e underlying fundamental theory. We find that both terms are necessary to determine dynamically the gravitino mass. Other useful constraints for the low energy phenomenology are also obtained.
