“…The issue of moduli stabilization also has important implications for supersymmetry breaking and the cosmological constant. Considerable progress has been made in the field of moduli stabilization within various corners of string theory, such as Type IIA [3,27,42,70,72], Type IIB [11, 36, 40, 41, 58, JHEP12(2010)056 60,64,65], Heterotic [13,29,38,55,67] and G 2 compactifications of M theory [2,[4][5][6]30]. The simplest recipe for moduli stabilization and constructing vacua with a small positive cosmological constant (de Sitter vacua) within Type IIB string theory was proposed by Kachru, Kallosh, Linde, and Trivedi [58] (KKLT).…”
