Fermion Doubling and Berenstein–Maldacena–Nastase Correspondence
نویسندگان
چکیده
We show that the string bit model suffers from doubling in the fermionic sector. The doubling leads to strong violation of supersymmetry in the limit N → ∞. Since there is an exact correspondence between string bits and the algebra of BMN operators even at finite N , doubling is expected also on the side of super-Yang–Mills theory. We discuss the origin of the doubling in the BMN sector.

Large angular momentum closed strings colliding with D-branes
We investigate colliding processes of closed strings with large angular momenta with D-branes. We give explicit CFT calculations for closed string states with an arbitrary number of bosonic excitations and no or one fermion excitation. The results reproduce the correspondence between closed string states and single trace operators in the boundary gauge theory recently suggested by Berenstein, M...

متن کاملDerivation of String Field Theory from the Large N BMN Limit
We continue the development of a systematic procedure for deriving closed string pp wave string field theory from the large N Berenstein-Maldacena-Nastase limit. In the present paper the effects of the Yang-Mills interaction are considered in detail for general BMN states. The SFT interaction with the appropriate operator insertion at the interaction point is demonstrated.
متن کاملSuperstring on PP - Wave Orbifold from Large - N Quiver Gauge Theory ∗
We extend the proposal of Berenstein, Maldacena and Nastase to Type IIB superstring propagating on pp-wave over R/Zk orbifold. We show that first-quantized free string theory is described correctly by the large N , fixed gauge coupling limit of N = 2 [U(N)] quiver gauge theory. We propose a precise map between gauge theory operators and string states for both untwisted and twisted sectors. We a...
متن کاملA Calculation of the plane wave string Hamiltonian from N = 4 super-Yang-Mills theory
Berenstein, Maldacena, and Nastase have proposed, as a limit of the strong form of the AdS/CFT correspondence, that string theory in a particular plane wave background is dual to a certain subset of operators in the N = 4 super-Yang-Mills theory. Even though this is a priori a strong/weak coupling duality, the matrix elements of the string theory Hamiltonian, when expressed in gauge theory vari...
