Query: Minkowski 3-forms, Flux String Vacua, Axion Stability and Naturalness   We discuss the role of Minkowski 3-forms in flux string vacua. In these vacua
all internal closed string fluxes are in one to one correspondence with
quantized Minkowski 4-forms. By performing a dimensional reduction of the
$D=10$ Type II supergravity actions we find that the 4-forms act as auxiliary
fields of the Kahler and complex structure moduli in the effective action. We
show that all the RR and NS axion dependence of the flux scalar potential
appears through the said 4-forms. Gauge invariance of these forms then severely
restricts the structure of the axion scalar potentials. Combined with duality
symmetries it suggests that all perturbative corrections to the leading axion
scalar potential $V_0$ should appear as an expansion in powers of $V_0$ itself.
These facts could have an important effect e.g. on the inflaton models based on
F-term axion monodromy. We also suggest that the involved multi-branched
structure of string vacua provides for a new way to maintain interacting scalar
masses stable against perturbative corrections.
