Massless S matrices for AdS3/CFT2
نویسندگان
چکیده
The AdS3/CFT2 correspondence features massless non-relativistic modes on the string worldsheet in lightcone gauge. We study detail these excitations and highlight how they naturally split between chiral (left-moving) anti-chiral (right-moving) representations. In light of this we discuss constraints two-particle S matrix imposed by braiding physical unitarity, parity, time-reversal, crossing invariance. also comment implication mirror kinematics.

Massless Particle Fields, with Momentum Matrices
Nontrivial translation matrices occur for spin (A,B) ⊕ (C,D) with | A − C | = | B−D | = 1/2, necessarily associating a (C,D) field with a spin (A,B) field. Including translation matrices in covariant non-unitary Poincaré representations also introduces new gauge terms in the construction of massless particle fields from canonical unitary fields. In the usual procedure without spacetime translat...
متن کاملS-constrained random matrices
Let S be a set of d-dimensional row vectors with entries in a q-ary alphabet. A matrix M with entries in the same q-ary alphabet is S-constrained if every set of d columns ofM contains as a submatrix a copy of the vectors in S, up to permutation. For a given set S of d-dimensional vectors, we compute the asymptotic probability for a random matrix M to be S-constrained, as the numbers of rows an...
متن کاملDeriving boundary S matrices
We show how to derive exact boundary S matrices for integrable quantum field theories in 1+1 dimensions using lattice regularization. We do this calculation explicitly for the sine-Gordon model with fixed boundary conditions using the Bethe ansatz for an XXZtype spin chain in a boundary magnetic field. Our results agree with recent conjectures of Ghoshal and Zamolodchikov, and indicate that the...
متن کاملConserved currents of massless fields of spin s ≥ 1 / 2
A complete and explicit classification of all locally constructed conserved currents and underlying conserved tensors is obtained for massless linear symmetric spinor fields of any spin s ≥ 1/2 in four dimensional flat spacetime. These results generalize the recent classification in the spin s = 1 case of all conserved currents locally constructed from the electromagnetic spinor field. The pres...
متن کاملConsistency Conditions on S-Matrix of Spin 1 Massless Particles
Motivated by new techniques in the computation of scattering amplitudes of massless particles in four dimensions, like BCFW recursion relations, the question of how much structure of the S-matrix can be determined from purely S-matrix arguments has received new attention. The BCFW recursion relations for massless particles of spin 1 and 2 imply that the whole tree-level S-matrix can be determin...
