PP Wave Limit and Enhanced Supersymmetry in Gauge Theories
, 2008
"... We observe that the pp wave limit of AdS5 × M 5 compactifications of type IIB string theory is universal, and maximally supersymmetric, as long as M 5 is smooth and preserves some supersymmetry. We investigate a specific case, M 5 = T 1,1. The dual N = 1 SCFT, describing D3branes at a conifold sing ..."

The large N limit of superconformal field theories and supergravity
, 1998
"... We show that the large N limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of AntideSitter spacetimes, spheres and other compact manifolds. This is shown by taking some branes in the full M/string theory and ..."

and then taking a low energy limit where the field theory on the brane decouples from the bulk. We observe that, in this limit, we can still trust the near horizon geometry for large N. The enhanced supersymmetries of the near horizon geometry correspond to the extra supersymmetry generators present
Superstring vacua of 4dimensional ppwaves with enhanced supersymmetry
 JHEP
"... We study the superstring vacua constructed from the conformal field theories of the type H4 × M, where H4 denotes the super NappiWitten model (super WZW model on the 4dimensional Heisenberg group H4) and M denotes an arbitrary N = 2 rational superconformal field theory with c = 9. We define (type ..."

We study the superstring vacua constructed from the conformal field theories of the type H4 × M, where H4 denotes the super NappiWitten model (super WZW model on the 4dimensional Heisenberg group H4) and M denotes an arbitrary N = 2 rational superconformal field theory with c = 9. We define (type II) superstring vacua with 8 supercharges, which are twice as many as those on the backgrounds of H4 × CY3. We explicitly construct as physical vertices the spacetime SUSY algebra that is a natural extension of H4 Lie algebra. The spectrum of physical states is classified into two sectors: (1) strings freely propagating along the transverse plane of ppwave geometry and possessing the integral U(1)Rcharges in M sector, and (2) strings that do not freely propagate along the transverse plane and possess the fractional U(1)Rcharges in M. The former behaves like the string excitations in the usual CalabiYau compactification, but the latter defines new sectors without changing the physics in “bulk ” space. We also analyze the thermal partition functions of these systems, emphasizing the similarity to the DLCQ string theory. As a byproduct we prove the supersymmetric cancellation of conformal blocks in an arbitrary unitary N = 2 SCFT of c = 12 with the suitable GSO projection. 1
IPhTt13/005 LPTENS 13/01 Enhanced supersymmetry from vanishing Euler number
"... We argue that compactifications on CalabiYau threefolds with vanishing Euler number yield effective four dimensional theories exhibiting (spontaneously broken) N = 4 supersymmetry. To this end, we derive the lowenergy effective action for general SU(2) structure manifolds in type IIA string theor ..."

ENHANCEMENT OF SUPERSYMMETRY
, 1996
"... Geometric Killing spinors which exist on AdSp+2 × S d−p−2 sometimes may be identified with supersymmetric Killing spinors. This explains the enhancement of unbroken supersymmetry near the pbrane horizon in d dimensions. The corresponding pbrane interpolates between two maximally supersymmetric vac ..."

"... We study the supersymmetry enhancement of ABJM theory.
