Semi-direct Gauge-Yukawa Mediation
Zhaofeng Kang, Tianjun Li, Tao Liu +1
We propose semi-direct Gauge-Yukawa mediation of supersymmetry (SUSY) breaking. The messenger fields mediating SUSY breaking to the visible sector do not directly couple with the g…
The Golden Strip of Correlated Top Quark, Gaugino, and Vectorlike Mass In No-Scale, No-Parameter F-SU(5)
Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos +1
We systematically establish the hyper-surface within the tan(beta), top quark mass m_t, universal gaugino mass M_1/2, and vectorlike mass M_V parameter volume which is compatible w…
SU(7) Unification of SU(3)_C*SU(4)_W* U(1)_{B-L}
Csaba Balázs, Tianjun Li, Fei Wang +1
We propose the SUSY SU(7) unification of the SU(3)_C* SU(4)_W* U(1)_{B-L} model. Such unification scenario has rich symmetry breaking chains in a five-dimensional orbifold. We stud…
Light Dark Matter from the U(1)_X Sector in the NMSSM with Gauge Mediation
Zhaofeng Kang, Tianjun Li, Tao Liu +2
Cosmic ray anomalies observed by PAMELA and Fermi-LAT experiments may be interpreted by heavy (TeV-scale) dark matter annihilation enhanced by Sommerfeld effects mediated by a very…
Decaying Dark Matter in the Supersymmetric Standard Model with Freeze-in and Seesaw mechanims
Zhaofeng Kang, Tianjun Li
Inspired by the decaying dark matter (DM) which can explain cosmic ray anomalies naturally, we consider the supersymmetric Standard Model with three right-handed neutrinos (RHNs) a…
The Golden Point of No-Scale and No-Parameter -SU(5)
Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos +1
The -lipped Grand Unified Theory (GUT) supplemented by TeV-scale vector-like particles from -theory, together dubbed -SU(5), offe…
