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 …
Bino-Higgsino Mixed Dark Matter in a Focus Point Gaugino Mediation
Tsutomu T. Yanagida, Norimi Yokozaki
We investigate the neutralino dark matter in the focus point gaugino mediation model with the O(100) GeV gravitino. The thermal relic abundance of the neutralino with a sizable Hig…
Higgs Boson Mass in Low Energy SUSY Models with Vector-like Matters
Norimi Yokozaki
We show that the gauge mediation models with vector-like matters can explain the Higgs boson mass of 126 GeV without large soft scalar masses nor a large left-right mixing of the s…
Recent Result of the AMS-02 Experiment and Decaying Gravitino Dark Matter in Gauge Mediation
Masahiro Ibe, Sho Iwamoto, Shigeki Matsumoto +2
The AMS-02 collaboration has recently reported an excess of cosmic-ray positron fractions, which is consistent with previous results at PAMELA and Fermi-LAT experiments. The result…
A natural scenario for heavy colored and light uncolored superpartners
Gautam Bhattacharyya, Biplob Bhattacherjee, Tsutomu T. Yanagida +1
Influenced by the current trend of experimental data, especially from the LHC, we construct a supersymmetric scenario where a natural dynamics makes the squarks and gluino super-he…
Muon g-2 and 125 GeV Higgs in Split-Family Supersymmetry
Masahiro Ibe, Tsutomu T. Yanagida, Norimi Yokozaki
We discuss the minimal supersymmetric standard model with "split-family" spectrum where the sfermions in the first two generations are in the hundreds GeV to a TeV range while the…
