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.
