Top quark three-body decays in R-violating MSSM

Heng,Z; Lu,G; Wu,L; Yang,JM
Subjects:

In the minimal supersymmetric standard model the R-parity violating interactions can trigger various exotic three-body decays for the top quark, which may be accessible at the LHC. In this work we examine the R-violating decays t-> c X_1 X_2, which includ

Top quark forward-backward asymmetry at the Tevatron: A Comparative study in different new physics models

Cao,J; Heng,Z; Wu,L; Yang,JM
Subjects:

The top quark forward-backward asymmetry A_{FB}^{t} measured at the Tevatron is above the Standard Model prediction by more than 2-sigma deviation, which might be a harbinger for new physics. In this work we examine the new physics contribution to A_{FB}^

Rare Z-decay into light CP-odd Higgs bosons: a comparative study in different new physics models

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

Various new physics models predict a light CP-odd Higgs boson (labeled as aaa) and open up new decay modes for Z-boson, such as Z→f?faZ→f?faZ \to \bar{f} f a, Z→aγZ→aγZ\to a\gamma and Z→aaaZ→aaaZ\to aaa, which could be explored at the GigaZ option of the

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

Current experimental constraints on the lightest Higgs boson mass in the constrained MSSM

Cao,J; Heng,Z; Li,D; Yang,JM
Subjects:

We examine the parameter space of the constrained MSSM by considering various experimental constraints. For the dark matter sector, we require the neutralino dark matter to account for the relic density measured by the WMAP and satisfy the XENON limits on

A SM-like Higgs near 125 GeV in low energy SUSY: a comparative study for MSSM and NMSSM

Cao,J; Heng,Z; Yang,JM; Zhang,Y; Zhu,J
Subjects:

Motivated by the recent LHC hints of a Higgs boson around 125 GeV, we assume a SM-like Higgs with the mass 123-127 GeV and study its implication in low energy SUSY by comparing the MSSM and NMSSM. We consider various experimental constraints at 2-sigma le

Higgs decay to dark matter in low energy SUSY: is it detectable at the LHC ?

Cao,J; Heng,Z; Yang,JM; Zhu,J
Subjects:

Due to the limited statistics so far accumulated in the Higgs boson search at the LHC, the Higgs boson property has not yet been tightly constrained and it is still allowed for the Higgs boson to decay invisibly to dark matter with a sizable branching rat

Status of low energy SUSY models confronted with the LHC 125 GeV Higgs data

Cao,J; Heng,Z; Yang,JM; Zhu,J
Subjects:

Confronted with the LHC data of a Higgs boson around 125 GeV, different models of low energy SUSY show different behaviors: some are favored, some are marginally survived and some are strongly disfavored or excluded. In this note we update our previous sc

Pair Production of a 125 GeV Higgs Boson in MSSM and NMSSM at the LHC

Cao,J; Heng,Z; Shang,L; Wan,P; Yang,JM
Subjects:

In light of the recent LHC Higgs search data, we investigate the pair production of a SM-like Higgs boson around 125GeV in the MSSM and NMSSM. We first scan the parameter space of each model by considering various experimental constraints, and then calcul

B meson dileptonic decays in the next-to-minimal supersymmetric model with a light CP-odd Higgs boson

Heng,Z; Oakes,R; Wang,W; Xiong,Z; Yang,JM
Subjects: Physics >> General Physics: Statistical and Quantum Mechanics, Quantum Information, etc.

In the next-to-minimal supersymmetric model (NMSSM) a light CP-odd Higgs boson is so far allowed by current experiments, which, together with a large tanβtan?β\tan\beta, may greatly enhance the rare dileptonic decays B\to X_s l^+ l^- and B_s\to l^+ l^- \g
