Superloop Equations and Two Dimensional Supergravity

چکیده
We propose a discrete model whose continuum limit reproduces the string susceptibility and the scaling dimensions of (2, 4m)-minimal superconformal models coupled to 2D-supergravity. The basic assumption in our presentation is a set of super-Virasoro constraints imposed on the partition function. We recover the Neveu-Schwarz and Ramond sectors of the theory, and we are also able to evaluate all planar loop correlation functions in the continuum limit. We find evidence to identify the integrable hierarchy of non-linear equations describing the double scaling limit as a supersymmetric generalization of KP studied by Rabin. ⋆ Permanent address: Departamento de F́ısica, Facultad de Ciencias, Universidad del Páıs Vasco, 48080 Bilbao, Spain

Double Scaling Limit of the Supervirasoro Constraints
⋆ Permanent address: Universität Bonn, Physikalisches Institut, Nussallee 12, W-5300 Bonn 1, Germany. We obtain the double scaling limit of a set of superloop equations recently proposed to describe the coupling of two-dimensional supergravity to minimal superconformal matter of type (2, 4m). The continuum loop equations are described in terms of a ĉ = 1 theory with a Z2-twisted scalar field an...
متن کاملHidden Symmetries of Large N QCD
The new symmetry of the loop dynamics of QCD is found. This is a local SUSY s = (s); = (s) of the superloop eld X (s; ) = x (s) + (s). The remarkable thing is, there is no einbein-gravitino on this theory, which makes it a 1D topological supergravity, or locally SUSY quantum mechanics. Using this symmetry, we derive the large Nc loop equation in momentum superloop space. Introducing as before t...
متن کاملNon - Perturbative Approach to 2 D - Supergravity and Super - Virasoro Constraints ⋆
⋆ PhD Thesis at the University of Bonn. The coupling of N = 1 superconformal field theories of type (4m, 2) to twodimensional supergravity can be formulated non-perturbatively in terms of a discrete super-eigenvalue model proposed by Alvarez-Gaumé, Itoyama, Mañes and Zadra. We derive the superloop equations that describe, in the double scaling limit, the non-perturbative solution of this model....

The new symmetry of the loop dynamics of QCD is found. This is a local SUSY δs = θβ(s), δθ = β(s) of the superloop field Xμ(s, θ) = xμ(s) + θψμ(s). The remarkable thing is, there is no einbein-gravitino on this theory, which makes it a 1D topological supergravity, or locally SUSY quantum mechanics. Using this symmetry, we derive the large Nc loop equation in momentum superloop space. Introducin...
متن کاملNonperturbative Solution of the Super-virasoro Constraints
We present the solution of the discrete super-Virasoro constraints to all orders of the genus expansion. Integrating over the fermionic variables we get a representation of the partition function in terms of the one-matrix model. We also obtain the nonperturbative solution of the super-Virasoro constraints in the double scaling limit but do not find agreement between our flows and the known sup...
