“…In the gauge/gravity correspondence, the background geometry of the string theory is expected to be emergent in the strong coupling limit of the corresponding gauge theory [26][27][28]. Though field configurations on the gauge theory side are considered to encode the information of the background geometry, a general prescription to see this is not known yet.…”

We propose a novel method of finding the classical limit of the matrix geometry. We define coherent states for a general matrix geometry described by a large-N sequence of D Hermitian matrices X µ (µ = 1, 2, · · · , D) and construct a corresponding classical space as a set of all coherent states. When the classical space forms a smooth manifold, we also express various geometric objects on the classical space such as the metric, Levi-Civita connection, curvature and Poisson tensor, in terms of the matrix elements. This method provides a new class of observables in matrix models, which characterize geometric properties of matrix configurations.

Abstract:We analyze the observational potential of single t production in both the t → bW and t → th decay channels at 8 TeV LHC using an integrated luminosity of 25 fb −1 . Our analysis is based on a simplified model with minimal coset SO(5)/SO(4) in which the t is a singlet of the unbroken SO(4). The single t production, as a consequence of electroweak symmetry breaking, is less kinematically suppressed, associated with a light forward jet and has boosted decay products at the 8 TeV LHC. Therefore it provides the most promising channel in searching for a heavy t . We have exploited the above kinematical features and used the jet substructure method to reconstruct the boosted Higgs in th decay channel. It is shown that a strong constraint on the t bW coupling (g t bW /g tbW,SM < 0.2 ∼ 0.3) at the 95% C. L. can be obtained for m t ⊂ (700, 1000) GeV.

“…The natural NMSSM may leave hints at the light stop sector, but the LHC search is rather model dependent [8,9] and barely has any relations with Higgs sector (Recently, an attempt to search for the light stop utilizing the properties of the SM-like Higgs boson was done in Ref.

After the discovery of a Standard Model (SM) like Higgs boson, naturalness strongly favors the next to the Minimal Supersymmetric SM (NMSSM). In this letter, we point out that the natural NMSSM usually predicts the following CP-even Higgs Hi sector: (A) H2 is the SM-like Higgs boson with mass pushed-upward by a lighter H1 with mass overwhelmingly within [mH 2 /2, mH 2 ]; (B) mH 3 ≃ 2µ/ sin 2β 300 GeV; (C) H3 has a significant coupling to top quark and can decay to H1H2 with a large branching ratio. Using jet substructure we show that all these three Higgs bosons can be discovered via gg → H3 → H1H2 → bbℓνjj at the 14 TeV LHC. Especially, the LEP-LHC scenario with H1 ≃ 98 GeV has a very good discovery potential.PACS numbers: 12.60. Jv, 14.70.Pw, 95.35.+d Introduction: Supersymmetry provides the most elegant solution to the gauge hierarchy problem in the Standard Model (SM). In the supersymmetric SMs (SSMs) with R-parity, we can not only achieve the gauge coupling unification, but also have a cold dark matter candidate. Recently, the discovery of a SM like Higgs boson at the LHC with mass m h around 126 GeV [1] has deep implications to the SSMs. Although such a relatively heavy Higgs boson mass can be achieved in the Minimal SSM (MSSM), it generically incurs a large fine-tuning (For the possible solutions, see [2].). By contrast, the next-to-the MSSM (NMSSM) with an extra SM singlet Higgs field S is strongly favored by naturalness [3], due to originally its dynamically solution to the Higgs bilinear mass µ problem and now the SM-like Higgs boson mass enhancement via the relatively large Higgs trilinear Yukawa coupling λ in the superpotential and singlet-doublet mixing effect [4][5][6][7]. The natural NMSSM may leave hints at the light stop sector, but the LHC search is rather model dependent [8, 9] and barely has any relations with Higgs sector (Recently, an attempt to search for the light stop utilizing the properties of the SM-like Higgs boson was done in Ref. [10].).In the natural NMSSM, the second lightest CP-even Higgs boson H 2 is identified as the SM like Higgs boson, while the lightest CP-even Higgs boson H 1 is dominated by singlet component. Thus, the H 2 mass can be pushed-upward via the singlet-doublet mixing effect [4][5][6][7]. Such a scenario can also explain the possible di-photon excess from Higgs decays [4,11,12] since the significant mixing effect reduces the decay width of
