Electroweak symmetry breaking and s-spectrum in M-theory Original Research Article

We study soft SUSY breaking parameters in M-theory with and without 5-brane moduli fields. We investigate successful electroweak symmetry breaking and the positivity of stau mass squared. A value of α(T+T̄) is phenomenologically constrained. Also we have phenomenological constraints on magnitudes of derivatives of the Kähler potential for the 5-brane moduli field. We study mass spectra in the allowed regions.
