Cosmological Constraints on Decaying Dark Matter
Santiago De Lope Amigo, William Man-Yin Cheung, Zhiqi Huang +1
We present a complete analysis of the cosmological constraints on decaying dark matter. Previous analyses have used the cosmic microwave background and Type Ia supernova. We have u…
QCD Corrections to K-Kbar Mixing in R-symmetric Supersymmetric Models
Andrew E. Blechman, Siew-Phang Ng
The leading-log QCD corrections to K-Kbar mixing in R-symmetric supersymmetric models are computed using effective field theory techniques. The spectrum topology where the gluino i…
Dark Matter in Gauge Mediation from Emergent Supersymmetry
Siew-Phang Ng, Nobuchika Okada
We investigated the viability of neutralino dark matter in the gauge mediation from emergent supersymmetry proposal. In this proposal, supersymmetry is broken at Planck scale and c…
Classical Cancellation of the Cosmological Constant Re-Considered
Stephen M. Barr, Siew-Phang Ng, Robert J. Scherrer
We revisit a scenario in which the cosmological constant is cancelled by the potential energy of a slowly evolving scalar field, or "cosmon". The cosmon's evolution is tied to the…
Gauge Mediation from Emergent Supersymmetry
Hock-Seng Goh, Siew-Phang Ng, Nobuchika Okada
We explore the possibility of gauge mediation in a paradigm whereby supersymmetry is posited to be an accidental symmetry of Nature and the Standard Model fields are composite boun…
Hybrid Inflation, Dark Energy And Dark Matter
Qaisar Shafi, Arunansu Sil, Siew-Phang Ng
It has been suggested that the dark energy density ρ_v ~ 10^{-12} eV^4 in the universe is associated with a metastable (false) vacuum, while the true vacuum has a vanishing cosmolo…
