Abstract:
Some of the soft SUSY breaking parameters in hidden sector supergravity model depend on the expectation value of the hidden sector scalar potential, , whose tree level value is equal to the tree level cosmological constant. The current practice of calculating soft parameters assumes that . Quantum correction to the cosmological constant can differ from the correction to by an amount of order . This implies that, for the vanishing cosmological constant, the --dependent parts of soft terms can be sizable, and hence the supergravity phenomenology should be accordingly modified.- supergravity
- supersymmetry: symmetry breaking
- potential: scalar
- cosmological constant
- correction: higher-order
