In the context of the LARGE volume scenario, stabilization of axionic moduli is revisited. This includes both even and odd axions with their scalar potential being generated by F-term contributions via various tree-level and non-perturbative effects like fluxed E3-brane instantons and fluxed poly-instantons. In all the cases, we estimate the decay constants and masses of the axions involved.
Comments: 35 pages, 3 figures, version3, Title changed along with significant changes in the introduction to stress that implementing a 'concrete' visible sector was not among the goals to achieve in this article, version to appear in NPB
