A Note on Bounds of Scalar Operators in Perturbative SCFTs
Sibo Zheng
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 wh…
Is There Scale Invariance in N=1 Supersymmetric Field Theories ?
Sibo Zheng
In two dimensions, it is well known that the scale invariance can be considered as conformal invariance. However, there is no solid proof of this equivalence in four or higher dime…
Variant Supercurrents and Linearized Supergravity
Sibo Zheng, Jia-Hui Huang
In this paper the variant supercurrents based on consistency and completion in off-shell N=1 supergravity are studied. We formulate the embedding relations for supersymmetric curre…
Constrained Superfields and Standard Realization of Nonlinear Supersymmetry
Hui Luo, Mingxing Luo, Sibo Zheng
A constrained superfield formalism has been proposed recently to analyze the low energy physics related to Goldstinos. We prove that this formalism can be reformulated in the langu…
E2 Instanton Effects and Higgs Physics In Intersecting Brane Models
Mingxing Luo, Sibo Zheng
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, th…
Black Holes in the Presence of Cosmological Constant and Large N Brane World
Mingxing Luo, Sibo Zheng
Analytic form has been obtained for four-dimensional black holes with a minimal Hawking temperature in a theory with cosmological constant, dilaton and gauge fields. In general dim…
