We examine the structure of soft supersymmetry breaking terms in KKLT models of flux compactification with low energy supersymmetry. Moduli are stabilized by fluxes and nonperturbative dynamics while… (More)

We extend the KKLT [1] approach to moduli stabilization by including the dilaton and the complex structure moduli into the effective supergravity theory. Decoupling of the dilaton is neither always… (More)

We present a detailed study of the collider observable mT2 applied for pair-produced superparticles decaying to visible particles and a pair of invisible lightest supersymmetric particles (LSPs).… (More)

Hadronic axions with the decay constant fa ≃ 10 GeV may fulfill all astrophysical and laboratory constraints discussed so far. In this paper, we reexamine the possibility of the hadronic axion window… (More)

A slow-rolling scalar field (Q ≡ Quintessence) with potenial energy VQ ∼ (3 × 10−3 eV)4 has been proposed as the origin of accelerating universe at present. We investigate the effective potential of… (More)

We examine the possibility that the strong CP problem is solved by stringtheoretic axions in strong-coupling limit of the E8×E 8 heterotic string theory (M -theory). We first discuss some generic… (More)

In some string compactifications, for instance the recently proposed KKLT set-up, light moduli are stabilized by nonperturbative effects at supersymmetric AdS vacuum which is lifted to a dS vacuum by… (More)

We examine the effects of anomalous U(1)A gauge symmetry on soft supersymmetry breaking terms while incorporating the stabilization of the modulus-axion multiplet responsible for the Green-Schwarz… (More)

We provide a simple macroscopic analysis of the four-dimensional effective supergravity of the Hořava-Witten M -theory which is expanded in powers of κ2/3/ρV 1/3 and κ2/3ρ/V 2/3 where κ2, V and ρ… (More)

We examine the Higgs mass parameters and electroweak symmetry breaking in supersymmetric orbifold field theories in which the 4-dimensional Higgs fields originate from higher-dimensional gauge… (More)
