Solving the Cosmic Lithium Problems with Gravitino Dark Matter in the CMSSM
Karsten Jedamzik, Ki-Young Choi, Leszek Roszkowski +1
Standard Big Bang nucleosynthesis at baryonic density as inferred by WMAP implies a primordial Li7 abundance factor of two to three larger than that inferred by observations of low…
Moduli stabilization and the pattern of soft SUSY breaking terms
Kiwoon Choi
In string compactification preserving N=1 SUSY, moduli fields are plausible candidates for the messenger of SUSY breaking at low energy scales. In a scenario that moduli-mediated S…
Little SUSY hierarchy in mixed modulus-anomaly mediation
Kiwoon Choi, Kwang Sik Jeong, Tatsuo Kobayashi +1
Motivated by the KKLT string compactification involving a supersymmetry-breaking uplifting potential, we examine 4D effective supergravity with a generic form of uplifting potentia…
Phenomenology of Mixed Modulus-Anomaly Mediation in Fluxed String Compactifications and Brane Models
Kiwoon Choi, Kwang Sik Jeong, Ken-ichi Okumura
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 lifte…
Soft Supersymmetry Breaking in KKLT Flux Compactification
Kiwoon Choi, Adam Falkowski, Hans Peter Nilles +1
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 nonperturba…
