A bstract The large number of moduli fields arising in a generic string theory compactification makes complete computation the low energy effective infeasible. common strategy to solve this problem is consider Calabi-Yau manifolds with discrete symmetries, which effectively reduce and make truncated Effective Field Theory possible. In approach, however, couplings (e.g., masses) are left undetermined. present paper we discuss tree-level mass spectrum type-IIB flux compactifications at Large Complex Structure, focusing on models reduced one-dimensional complex structure sector. We compute for dilaton moduli, including , can be expressed entirely terms known theory. show that masses set naturally heavy vacua consistent KKLT construction, other phenomenologically interesting scenarios where involves much lighter than gravitino. also derive probability distribution ensemble vacua, it exhibits universal features independent details compactification. check our results sample constructed an orientifold $$ {\mathbbm{W}\mathrm{\mathbb{P}}}_{\left[1,1,1,1,4\right]}^4 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:msubsup><mml:mrow><mml:mi>W</mml:mi><mml:mi>ℙ</mml:mi></mml:mrow><mml:mfenced><mml:mn>1</mml:mn><mml:mn>1</mml:mn><mml:mn>1</mml:mn><mml:mn>1</mml:mn><mml:mn>4</mml:mn></mml:mfenced><mml:mn>4</mml:mn></mml:msubsup></mml:math> . Finally, conditions under derived here could arise more general compactifications.
