On the S-matrix of Liouville theory [PDF]

open access: yesJournal of High Energy Physics, 2021
The S-matrix for each chiral sector of Liouville theory on a cylinder is computed from the loop expansion of correlation functions of a one-dimensional field theory on a circle with a non-local kinetic energy and an exponential potential.

The L ∞-algebra of the S-matrix [PDF]

open access: yesJournal of High Energy Physics, 2019
We point out that the one-particle-irreducible vacuum correlation functions of a QFT are the structure constants of an L ∞-algebra, whose Jacobi identities hold whenever there are no local gauge anomalies.

Towards a nonperturbative construction of the S-matrix

open access: yesJournal of High Energy Physics, 2023
We present a nonperturbative recipe for directly computing the S-matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and can be applied to a wide range of theories, including potentially QCD.

Spinning S-matrix bootstrap in 4d

open access: yesJournal of High Energy Physics, 2022
We review unitarity and crossing constraints on scattering amplitudes for particles with spin in four dimensional quantum field theories. As an application we study two to two scattering of neutral spin 1/2 fermions in detail.

The soft S $$ \mathcal{S} $$ -matrix in gravity

open access: yesJournal of High Energy Physics, 2020
The gravitational S $$ \mathcal{S} $$ -matrix defined with an infrared (IR) cutoff factorizes into hard and soft factors. The soft factor is universal and contains all the IR and collinear divergences.

Analyticity and the holographic S-matrix [PDF]

open access: yesJournal of High Energy Physics, 2012
Abstract We derive a simple relation between the Mellin amplitude for AdS/CFT correlation functions and the bulk S-Matrix in the flat spacetime limit, proving a conjecture of Penedones. As a consequence of the Operator Product Expansion, the Mellin amplitude for any unitary CFT must be a meromorphic function with simple poles on ...

Contour integrals and the modular S $$ \mathcal{S} $$ -matrix

open access: yesJournal of High Energy Physics, 2020
We investigate a conjecture to describe the characters of large families of RCFT’s in terms of contour integrals of Feigin-Fuchs type. We provide a simple algorithm to determine the modular S $$ \mathcal{S} $$ -matrix for arbitrary numbers of characters ...

S-matrix in permutation orbifolds

open access: yesJournal of Algebra, 2022
For a fixed positive integer $k$, any element $g$ of the permutation group $S_{k}$ acts on the tensor product vertex operator algebra $V^{\otimes k}$ in the obvious way. In this paper, we determine the $S$-matrix of $\left(V^{\otimes k}\right)^{G}$ if $G=\left\langle g\right\rangle $ is the cyclic group generated by $g=\left(1,\ 2,\cdots,k\right).$

The O(N) S-matrix monolith

open access: yesJournal of High Energy Physics, 2020
We consider the scattering matrices of massive quantum field theories with no bound states and a global O(N) symmetry in two spacetime dimensions. In particular we explore the space of two-to-two S-matrices of particles of mass m transforming in the ...
