Bridging positivity and S-matrix bootstrap bounds
Journal of High Energy Physics, 2023 The main objective of this work is to isolate Effective Field Theory scattering amplitudes in the space of non-perturbative two-to-two amplitudes, using the S-matrix Bootstrap.

Nanoscale precipitations in deformed dilute alloying Mg-Zn-Gd alloy
Materials & Design, 2020 Nanoscale precipitations in deformed dilute alloying Mg-Zn-RE alloys usually play critical positive roles in mechanical properties, while characterizing them still poses a significant challenge due to their small size and low volume fraction.

S matrix for a three-parameter integrable deformation of AdS 3 × S 3 strings
Journal of High Energy Physics, 2020 We consider the three-parameter integrable deformation of the AdS 3 × S 3 superstring background constructed in arXiv:1811.00453. Working on the string worldsheet in uniform lightcone gauge, we find the tree-level bosonic S matrix of the model and study ...

Unitarity and the holographic S-Matrix [PDF]
Journal of High Energy Physics, 2012 Abstract The bulk S-Matrix can be given a non-perturbative definition in terms of the flat space limit of AdS/CFT. We show that the unitarity of the S-Matrix, ie the optical theorem, can be derived by studying the behavior of the OPE and the conformal block decomposition in the flat space limit.

Selection rules for the S-Matrix bootstrap
SciPost Physics, 2021 We examine the space of allowed S-matrices on the Adler zeros' plane using the recently resurrected (numerical) S-matrix bootstrap program for pion scattering.

On the Nonrelativistic S-Matrix [PDF]
Progress of Theoretical Physics, 1983 Summary: Attention is drawn to older results from the literature from which it follows immediately that the \(S\)-matrices for the Korteweg-de Vries equation and for the related (stationary multicomponent) nonlinear Schrodinger equation factorize.

S-matrix bootstrap for resonances
Journal of High Energy Physics, 2018 We study the 2 → 2 S-matrix element of a generic, gapped and Lorentz invariant QFT in d = 1 + 1 space time dimensions. We derive an analytical bound on the coupling of the asymptotic states to unstable particles (a.k.a.

Celestial insights into the S-matrix bootstrap
Journal of High Energy Physics, 2022 We consider 2-2 scattering in four spacetime dimensions in Celestial variables. Using the crossing symmetric dispersion relation (CSDR), we recast the Celestial amplitudes in terms of crossing symmetric partial waves.
