Query: Linking Light Scalar Modes with A Small Positive Cosmological Constant
  in String Theory   Based on the studies in Type IIB string theory phenomenology, we conjecture
that a good fraction of the meta-stable de Sitter vacua in the cosmic stringy
landscape tend to have a very small cosmological constant $\Lambda$ when
compared to either the string scale $M_S$ or the Planck scale $M_P$, i.e.,
$\Lambda \ll M_S^4 \ll M_P^4$. These low lying de Sitter vacua tend to be
accompanied by very light scalar bosons/axions. Here we illustrate this
phenomenon with the bosonic mass spectra in a set of Type IIB string theory
flux compactification models. We conjecture that small $\Lambda$ with light
bosons is generic among de Sitter solutions in string theory; that is, the
smallness of $\Lambda$ and the existence of very light bosons (may be even the
Higgs boson) are results of the statistical preference for such vacua in the
landscape. We also discuss a scalar field $\phi^3/\phi^4$ model to illustrate
how this statistical preference for a small $\Lambda$ remains when quantum loop
corrections are included, thus bypassing the radiative instability problem.
