Abstract
We reconsider the dimension-11 Planck scale, the
physical scale of the eleventh dimension, the
physical scale of the
Calabi-Yau manifold
and the coupling in the hidden sector in M-theory on
S1/Z2. Also we discuss reasonable bounds on them.
Considering the F-term of the dilaton and moduli SUSY breaking
and choosing two representative points which
correspond to the scalar quasi-massless scenario and the
dilaton dominant SUSY breaking scenario,
respectively, we analyze experimental constraints on the parameter
space.
The sparticle spectrum and some phenomenological
predictions are also given.
