COSMOLOGICAL CONSTANT AND SOFT TERMS IN SUPERGRAVITY

Some of the soft supersymmetry breaking parameters in the hidden secto r supergravity model depend on the expectation value of the hidden sec tor scalar potential, [V-h], whose tree level value is equal to the tr ee level cosmological constant. The current practice of calculating so ft parameters assumes that [V-h] = 0. Quantum correction to the cosmol ogical constant can differ from the correction to [V-h] by an amount o f order m(3/2)(2)M(Pl)(2)/8 pi. This implies that, for the vanishing c osmological constant, the [V-h]-dependent parts of soft terms can be s izable, and hence the supergravity phenomenology should be accordingly modified.
