Constrained superfields and standard realization of nonlinear supersymmetry
A constrained superfield formalism has been proposed in  to analyze the low energy physics related to Goldstinos. We prove that this formalism can be reformulated in the language of standard realization of nonlinear supersymmetry. New relations have been uncovered in the standard realization of nonlinear supersymmetry.

title: On dark matter selected high-scale supersymmetry
abstract: A bstractThe prediction for the Higgs mass in the dark matter selected high-scale SUSY is explored. We show the bounds on SUSY-breaking scale in models of SM +w˜$$ +\tilde{w} $$ and SM +h˜/s˜$$ +\tilde{h}/\tilde{s} $$ due to the observed Higgs mass at the LHC. We propose that effective theory below scale m˜$$ \tilde{m} $$ described by SM +w˜$$ +\tilde{w} $$ is possibly realized in gauge mediation with multiple spurion fields that exhibit significant mass hierarchy, and that by SM +h˜/s˜$$ +\tilde{h}/\tilde{s} $$ can be realized with direct singlet-messenger-messenger coupling for singlet Yukawa coupling λ∼v/m˜1/2gSM$$ \lambda \sim {\left(v/\tilde{m}\right)}^{1/2}{g}_{\mathrm{SM}} $$. Finally, the constraint on high-scale SUSY is investigated in the light of inflation physics if these two subjects are directly related.

title: A note on bounds of scalar operators in perturbative SCFTs
abstract: Bounds on anomalous dimensions of scalar operators in 4D superconformal field theory are explored through perturbative viewpoint. Following the recent work of Green and Shih, in which a conjecture involved this issue is verified at the NLO, we consider the NNLO corrections to the bounds, which are important in some situations and can be divided into two cases where O ( λ 4 ) or O ( y 2 ) effects dominate respectively. In the former case, we find that the conjecture is maintained at NNLO, while in the later case the statement still holds due to null correction.

title: E2 Instanton Effects and Higgs Physics In Intersecting Brane Models
abstract: String instanton effects in Higgs physics are discussed through a type IIA model based on T^{6}/(Z^{2}\times Z^{'2}) orentifold compactifaction. By inclusion of rigid E2-branes, the model exhibits a MSSM-like spectrum, as well as extra mu and quartic Higgs couplings. These extra couplings are induced via E2 instantons non-perturbatively. Setting the string scale at 10^{18} GeV, one gets interesting TeV Higgs physics. In particlular, the tree-level Higgs mass can be uplifted substantially.

title: R-symmetric Gauge Mediation With Fayet-Iliopoulos Term
abstract: We have studied R-symmetrc gauge mediation models with Fayet-Iliopoulos terms. We give a concrete example of hidden sector with an U(1)H gauge theory and a Fayet-Iliopoulos term, which can induce distinctive soft terms in the visible sector, and help solving fine tuning problems in models of R-symmetric gauge mediation.

title: Phenomenologies of Higgs messenger models
abstract: In this paper, we investigate the phenomenologies of models where the Higgs sector plays the role of messengers in gauge mediation. The minimal Higgs sector and its extension are considered respectively. We find that there exist viable models when an appropriate parity is imposed. Phenomenological features in these kind of models include three approximate sum rules for scalar masses, light gluino as well as one-loop µ and two-loop Bµ terms.

title: The BES upgrade
abstract: The Beijing Spectrometer (BES) detector is a general purpose solenoid detector at the Beijing Electron Positron Collider (BEPC) in Beijing, China, that has collected large numbers of J/ψ, ψ′, D s , D and τ events. In this paper, we describe the recent upgrade of the initial BES detector (BESI) to the improved BESII detector.

title: SEARCH FOR LIGHT SUPERSYMMETRIC BARYONS
abstract: We have searched for the production and decay of light supersymmetric baryons produced in 800 GeV/c proton copper interactions in a charged hyperon beam experiment. We observe no evidence for the decays R{sup +}(uud{tilde g}){r_arrow} S{sup 0}(uds{tilde g}){pi}{sup +} and X{sup -}(ssd{tilde g}){r_arrow} S{sup 0}(uds{tilde g}){pi}{sup -} in the parent mass and lifetime ranges of 1700{endash}2500 MeV/c{sup 2} and 50{endash}500ps. Production upper limits for R{sup +} at x{sub F}=0.47, P{sub t}=1.4GeV/c{sup 2} and X{sup -} at x{sub F}=0.48, P{sub t}=0.65GeV/c{sup 2} of less than 10{sup -3} of all charged secondary particles produced are obtained for all but the highest masses and shortest lifetimes predicted.
