Iterative Structure of the N = 4 SYM Spin Chain
We develop algebraic methods for finding loop corrections to the N = 4 SYM dilatation generator, within the noncompact psu(1, 1|2) sector. This sector gives a ’t Hooft coupling λ-dependent representation of psu(1, 1|2)× psu(1|1)2. At first working independently of the representation, we present an all-order algebraic ansatz for the λ-dependence of this Lie algebra’s generators. The ansatz solve...
متن کاملThe N = 4 SYM Integrable Super Spin Chain
Recently it was established that the one-loop planar dilatation generator of N = 4 Super Yang-Mills theory may be identified, in some restricted cases, with the Hamiltonians of various integrable quantum spin chains. In particular Minahan and Zarembo established that the restriction to scalar operators leads to an integrable vector so(6) chain, while recent work in QCD suggested that restrictin...
متن کاملHigher Spin Symmetry and N = 4 SYM
We assemble the spectrum of single-trace operators in free N = 4 SU (N) SYM theory into irreducible representations of the Higher Spin symmetry algebra hs(2, 2|4). Higher Spin representations or YT-pletons are associated to Young tableaux (YT) corresponding to representations of the symmetric group compatible with the cyclicity of color traces. After turning on interactions g YM = 0, YT-pletons...
متن کاملOn the central charge extension of the N = 4 SYM spin chain
In this paper it is argued that the central charge extension of the Coulomb branch of N = 4 SYM theory appears as a limit of Beisert’s central charge extension of the planar N = 4 spin chain in the presence of boundaries. These boundaries are interpreted as D-branes that source the central charge and are realized as giant gravitons and dual giant gravitons in the AdS dual. The BPS states that c...
متن کاملHigher spin symmetry ( breaking ) in N = 4 SYM and holography ∗
I concisely review the results of [1–3] that shed some light on " La Grande Bouffe " 1 , the pantagruelic Higgs mechanism, whereby HS gauge fields in the AdS bulk eat lower spin Goldstone fields, and on its holographic implications such as the emergence of anomalous dimensions in the boundary N=4 SYM theory. Formulating the dynamics of higher spin (HS) fields is a long standing problem, see e.g...
