One-Loop Anomaly Mediated Scalar Masses and (g-2)_mu in Pure Gravity Mediation
Jason L. Evans, Masahiro Ibe, Keith A. Olive +1
We consider the effects of non-universalities among sfermion generations in models of Pure Gravity Mediation (PGM). In PGM models and in many models with strongly stabilized moduli…
A Closer Look at Gaugino Masses in Pure Gravity Mediation Model/Minimal Split SUSY Model
Keisuke Harigaya, Masahiro Ibe, Tsutomu T. Yanagida
We take a closer look at the gaugino masses in the context of pure gravity mediation models/minimal split SUSY models. We see that the gaugino mass spectrum has a richer structure…
A practical GMSB model for explaining the muon (g-2) with gauge coupling unification
Gautam Bhattacharyya, Biplob Bhattacherjee, Tsutomu T. Yanagida +1
We present a gauge mediated supersymmetry breaking model having weak SU(2) triplet, color SU(3) octet and SU(5) 5-plet messengers, that can simultaneously explain the muon …
Lower Bound on the Garvitino Mass TeV in -Symmetry Breaking New Inflation
Keisuke Harigaya, Masahiro Ibe, Tsutomu T. Yanagida
In supersymmetric theories, the symmetry plays a unique role in suppressing a constant term in the superpotential. In single chiral field models of spontaneous breaking of a di…
Chaotic Inflation with Right-handed Sneutrinos after Planck
Kazunori Nakayama, Fuminobu Takahashi, Tsutomu T. Yanagida
We propose a chaotic inflation model in which the lightest right-handed sneutrino serves as the inflaton and the predicted values of the spectral index and tensor-to-scalar ratio a…
Hypercharged Dark Matter and Direct Detection as a Probe of Reheating
Brian Feldstein, Masahiro Ibe, Tsutomu T. Yanagida
The lack of new physics at the LHC so far weakens the argument for TeV scale thermal dark matter. On the other hand, heavier, non-thermal dark matter is generally difficult to test…
