Realistic Flipped SU(5) from Orbifold SO(10)

Balazs,C; Kang,Z; Li,T; Wang,F; Yang,JM
分类:

We propose a realistic flipped SU(5) model derived from a five-dimensional orbifold SO(10) model. The Standard Model (SM) fermion masses and mixings are explained by combining the traditional Froggatt-Nielsen mechanism with the five-dimensional wave funct

SU(7) Unification of SU(3)CxSU(4)WxU(1)B?LSU(3)CxSU(4)WxU(1)B?LSU(3)_C x SU(4)_W x U(1)_{B-L}

Balazs,C; Li,T; Wang,F; Yang,JM
分类:

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 study in detail the SUSY SU(7) symmetry breaking into SU(3)_C* SU(4)_W* U(1)_{B

Natural SUSY from SU(5) Orbifold GUT

Han,C; Wang,F; Yang,JM
分类:

We propose a realistic 5D orbifold GUT model that can reduce to natural (or radiative natural) supersymmetry as the low energy effective theory. Supersymmetry as well as gauge symmetry are broken by the twist boundary conditions. We find that it is non-trivial to introduce other flavor symmetry other than the SU(2)R R-symmetry. We ameliorate the tension between the small number of free parameters and the successful electroweak symmetry breaking by introducing non-minimal Kahler potentials. A large trilinear term At, which is necessary to give a 125 GeV Higgs boson, is naturally provided in our scenario. A scan under current experimental constraints shows that our model can realize natural (or radiative natural) supersymmetry. Only radiative natural supersym- metry can naturally lead to 125 GeV higgs. Additional dark matter species other than neutralino(like axion) are needed to provide enough relic density. Relatively large stop masses are necessary to give realistic higg mass in most of the parameter spaces.

Split supersymmetry under GUT and current dark matter constraints

Wang,F; Wang,W; Yang,JM
分类:

We recalculate the two-loop beta functions for three gauge couplings taking into account all low energy threshold corrections in split supersymmetry (split-SUSY) which assumes a very high scalar mass scale MSMSM_S . We find that in split-SUSY with a gaugi

Singlet extension of the MSSM as a solution to the small cosmological scale anomalies

Wang,F; Wang,W; Yang,JM; Zhou,S
分类:

In this work we show that the general singlet extension of the minimal supersymmetric standard model (MSSM) can naturally provide a self-interacting singlino dark matter to solve the small cosmological scale anomalies (a large Sommerfeld enhancement facto

A split SUSY model from SUSY GUT

Wang,F; Wang,W; Yang,JM
分类:

We propose to split the sparticle spectrum from the hierarchy between the GUT scale and the Planck scale. A split supersymmetric model, which gives non-universal gaugino masses, is built with proper high dimensional operators in the framework of SO(10) GU

Reconcile muon g-2 anomaly with LHC data in SUGRA with generalized gravity mediation

Wang,F; Wang,W; Yang,JM
分类:

From generalized gravity mediation we build a SUGRA scenario in which the gluino is much heavier than the electroweak gauginos at the GUT scale. We find that such a non-universal gaugino scenario with very heavy gluino at the GUT scale can be naturally ob

Heavy colored SUSY partners from deflected anomaly mediation

Wang,F; Wang,W; Yang,JM; Zhang,Y
分类:

We propose a deflected anomaly mediation scenario from SUSY QCD which can lead to both positive and negative deflection parameters (there is a smooth transition between these two deflection parameter regions by adjusting certain couplings). Such a scenario can naturally give a SUSY spectrum in which all the colored sparticles are heavy while the sleptons are light. As a result, the discrepancy between the Brookheaven gμ − 2 experiment and LHC data can be reconciled in this scenario. We also find that the parameter space for explaining the gμ − 2 anomaly at 1σ level can be fully covered by the future LUX-ZEPLIN 7.2 Ton experiment.

750 GeV diphoton resonance in a top and bottom seesaw model

Kobakhidze,A; Wang,F; Wu,L; Yang,JM; Zhang,M
分类:

The top and bottom seesaw model, which extends the top seesaw in order to accommodate a 125 GeV Higgs boson, predicts vector-like top/bottom partners and these partners can be bounded to form several neutral and charged singlet composite scalars by some n

750 GeV diphoton resonance, 125 GeV Higgs and muon g ? 2 anomaly in deflected anomaly mediation SUSY breaking scenarios

Wang,F; Wu,L; Yang,JM; Zhang,M
分类:

We propose to interpret the 750 GeV diphoton excess in deflected anomaly mediation supersymmetry breaking scenarios, which can naturally predict couplings be- tween a singlet field and vector-like messengers. The CP-even scalar component (S) of the singlet field can serve as the 750 GeV resonance. The messenger scale, which is of order the gravitino scale, can be as light as Fφ ∼ O(10) TeV when the messenger species NF and the deflection parameter d are moderately large. Such messengers can induce the large loop decay process S → γγ. Our results show that such a scenario can successfully accommo- date the 125 GeV Higgs boson, the 750 GeV diphoton excess and the muon g − 2 without conflicting with the LHC constraints. We also comment on the possible explanations in the gauge mediation supersymmetry breaking scenario.
