| 英文摘要 | We reanalyse the computation of the cosmological constant Lambda at two loops in recently proposed superstring models without massless gravitini, both in the theta-function based formalism and by a detailed computation in the more explicit hyperelliptic description of the underlying genus two Riemann surface. Lambda is expressed as the integral over the surface moduli of an amplitude which is zero if SUSY is not completely broken, but we find it to be non vanishing in the SUSY breaking models which can be given an explicitly workable fermionic formulation. Thus unfortunately the issue of getting realistic and perturbatively viable models from Superstring Theory remains open. |
