Light Dark Matter from the U(1)XU(1)XU(1)_X Sector in the NMSSM with Gauge Mediation

Kang,Z; Li,T; Liu,T; Tong,C; Yang,JM
Subjects:

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 light (sub-GeV) U(1)_X gauge boson, while the recent direct searches from

Semi-direct Gauge-Yukawa Mediation

Kang,Z; Li,T; Liu,T; Yang,JM
Subjects:

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 goldstino field, and instead they have gauge and Yukawa interactions with so

The maximal U(1)LU(1)LU(1)_L inverse seesaw from d=5d=5d=5 operator and oscillating asymmetric Sneutrino dark matter

Kang,Z; Li,J; Li,T; Liu,T; Yang,JM
Subjects:

The maximal U(1)LU(1)LU(1)_L supersymmetric inverse seesaw mechanism (MLSIS) provides a natural way to relate asymmetric dark matter (ADM) with neutrino physics. In this paper we point out that MLSIS is a natural outcome if one dynamically realizes the in

Di-photon Higgs signal at the LHC: A comparative study in different supersymmetric models

Cao,J; Heng,Z; Liu,T; Yang,JM
Subjects:

As the most important discovery channel for a light Higgs boson at the LHC, the di-photon signal gg→h→γγ is sensitive to underlying physics. In this work we investigate such a signal in a comparative way by considering three different supersymmetric model

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

Kang,Z; Li,T; Liu,T; Yang,JM
Subjects:

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,JM
Subjects:

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

Higgs decay to goldstini and its observability at the LHC

Liu,T; Wang,L; Yang,JM
Subjects:

If supersymmetry is broken independently in multiple sectors with different scales, a number of goldstinos will be generated. One linear combination of these goldstinos is massless and eaten by the gravitino, while the orthogonal combinations acquire a tr

Pseudo-goldstino and electroweak gauginos at the LHC

Hikasa,K; Liu,T; Wang,L; Yang,JM
Subjects:

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,JM
Subjects:

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
