Super Yang - Mills Operators from the D 3 - brane Action in a Curved Background

چکیده
A consistent truncation of IIB on S 5 has been obtained in the sector of the metric and the 4-form potential. The ansatz contains 20 scalars and all 15 gauge fields of N = 8 gauged supergravity in five dimensions. With this fully non-linear ansatz, the calculations for n-point correlators of super Yang-Mills (SYM) theory via AdS/CFT are simpler than those in the literature that use the linear ansatz followed by non-linear field redefinitions. We work out the SYM operators that couple to the scalars by expanding the Dirac-Born-Infeld (DBI) action plus Wess-Zumino (WZ) terms around an AdS 5 × S 5 background with the metric fluctuations. The resulting operators agree with those based on a superconformal symmetry argument. We discuss the significance of our results.

Vertex Operators for Super Yang-Mills and Multi D-branes in Green-Schwarz Superstring
We study vertex operators for super Yang-Mills and multi D-branes in covariant form using Green-Schwarz formalism. We introduce the contact terms naturally and prove space-time supersymmetry and gauge invariance. The nonlinear realization of broken supersymmetry in the presence of D-branes is also discussed. The shift of fermionic coordinate δ(−)Ψ = η becomes exact symmetry of D-brane in the st...
متن کاملAdS/CFT EQUIVALENCE TRANSFORMATION
We show that any conformal field theory in d-dimensional Minkowski space, in a phase with spontaneously broken conformal symmetry and with the dilaton among its fields, can be rewritten in terms of the static gauge (d − 1)-brane on AdS(d+1) by means of an invertible change of variables. This nonlinear holographic transformation maps the Minkowski space coordinates onto the brane worldvolume one...

It...
متن کاملBrane Effective Actions, Kappa-Symmetry and Applications
This is a review on brane effective actions, their symmetries and some of their applications. Its first part covers the Green-Schwarz formulation of single M- and D-brane effective actions focusing on kinematical aspects: the identification of their degrees of freedom, the importance of world volume diffeomorphisms and kappa symmetry to achieve manifest spacetime covariance and supersymmetry, a...
متن کاملInstantons in Deformed Super Yang-Mills Theories
We study the instanton effective action in deformed four-dimensional N = 2 and N = 4 super Yang-Mills (SYM) theories. These deformed gauge theories are defined on the D-brane world-volume in the presence of constant, self-dual Ramond-Ramond (R-R) 3-form field strength background F which is scaled as (2πα′) 1 2F = fixed in the zero-slope limit α′ → 0. The instanton effective action is obtained b...
