The Minimal Solution to the mu/B_mu Problem in Gauge Mediation

Kang,Z; Li,T; Liu,T; Yang,JMSubjects:

We provide a minimal solution to the mu/B_mu problem in the gauge mediated supersymmetry breaking by introducing a Standard Model singlet filed S with a mass around the messenger scale which couples to the Higgs and messenger fields. This singlet is nearl |

A Heavy SM-like Higgs and a Light Stop from Yukawa-Deflected Gauge Mediation

Kang,Z; Li,T; Liu,T; Tong,C; Yang,JMSubjects:

To obtain a SM-like Higgs boson around 125 GeV in the Minimal Supersymmetric Standard Model with minimal gauge mediation of supersymmetry breaking (GMSB), a heavy stop at multi-TeV level is needed and incurs severe fine-tuning, which can be ameliorated in |

Pseudo-goldstino and electroweak gauginos at the LHC

Hikasa,K; Liu,T; Wang,L; Yang,JMSubjects:

The multi-sector SUSY breaking predicts the existence of pseudo-goldstino, which could couple more strongly to visible fields than ordinary gravitino. Then the lightest neutralino and chargino can decay into a pseudo-goldstino plus a Z-boson, Higgs boson |

Pseudo-goldstino and electroweakinos via VBF processes at LHC

Liu,T; Wang,L; Yang,JMSubjects:

The multi-sector SUSY breaking predicts pseudo-goldstino which can couple to the visible sector more strongly than the ordinary gravitino and thus induce the decays of the lightest neutralino and chargino (collectively called electroweakinos) inside the d |

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

Wang,F; Wang,W; Yang,JMSubjects:

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,YSubjects:

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. |

Radiative natural SUSY spectrum from deflected AMSB scenario with messenger-matter interactions

Wang,F; Yang,JM; Zhang,YSubjects:

A radiative natural SUSY spectrum are proposed in the deflected anomaly mediation scenario with general messenger-matter interactions. Due to the contributions from the new interactions, positive slepton masses as well as a large |Att_{t} | term can natur |

An extension for direct gauge mediation of metastable supersymmetry breaking

Xu, Fuqiang; Yang, Jin MinSubjects: Physics >> The Physics of Elementary Particles and Fields

We study the direct mediation of metastable supersymmetry breaking by a Phi(2)-deformation to the ISS model and extend it by splitting both Tr Phi and Tr Phi(2) terms in the superpotential and gauging the flavor symmetry. We find that with such an extension enough-long-lived metastable vacua can be obtained and the proper gaugino masses can be generated. Also, this allows for constructing a kind of models which can avoid the Landau pole problem. Especially, in our metastable vacua there exist a large region for the parameter m(3) which can satisfy the phenomenology requirements and allow for a low SUSY-breaking scale (h mu(2) similar to 100 TeV).
