Title: Statistics of M-theory vacua
Keywords: vacua;superstring;M-Theory
Issue Date: 2005
Publisher: American Institute of Physics
Description: We study the vacuum statistics of ensembles of <i>M</i> theory compactifications on G<sub>2</sub> holonomy manifolds with fluxes, and of ensembles of Freund-Rubin vacua. We discuss similarities and differences between these and Type IIB flux landscapes. For the G<sub>2</sub> ensembles, we find that large volumes are strongly suppressed, and for both, unlike the IIB case, the distribution of cosmological constants is non-uniform. We also argue that these ensembles typically have exponentially more non-supersymmetric than supersymmetric vacua, and show that supersymmetry is virtually always broken at a high scale.;Physics
