A scattering amplitude for massive particles in AdS
Journal of High Energy Physics, 2022 In this paper, we propose a conformally covariant momentum space representation of CFT correlation functions. We call it the AdS S-matrix. This representation has the property that it reduces to the S-matrix in the flat space limit.

Volume oscillation and acoustical scattering of a gas bubble [PDF]
MATEC Web of Conferences, 2019 The exact solution of a gas bubble’ volume was obtained based on volume oscillation of a gas bubble. The volume pulsation, acoustic impedance, scattering pressure of a gas bubble, acoustical power of scattering and acoustical scattering cross section of ...

Analyticity properties of scattering amplitude in theories with compactified space dimensions
Nuclear Physics B, 2019 We consider a massive scalar, neutral, field theory in a five dimensional flat spacetime. Subsequently, one spatial dimension is compactified on a circle, S1, of radius R.

Transient chaos analysis of string scattering
Journal of High Energy Physics, 2022 It has long been thought that a highly excited string can be regarded as a black hole: the correspondence principle between strings and a black hole, while recent studies found that black holes are characterized by chaos.

Chaotic scattering of highly excited strings
Journal of High Energy Physics, 2021 Motivated by the desire to understand chaos in the S-matrix of string theory, we study tree level scattering amplitudes involving highly excited strings. While the amplitudes for scattering of light strings have been a hallmark of string theory since its

Surface-Integral Approach to the Coulomb Few-Body Scattering Problem
EPJ Web of Conferences, 2010 We present main features of a surface-integral approach to the Coulomb few-body scattering problem. This approach is valid for both short-range and Coulombic longe-range interactions.

Scattering amplitudes from dispersive iterations of unitarity
Journal of High Energy Physics, 2023 We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions.

Four-gauge-particle scattering amplitudes and Polyakov string path integral in the proper-time gauge
Physics Letters B, 2019 We evaluate four-gauge-particle tree level scattering amplitudes using the Polyakov string path integral in the proper-time gauge, where the string path integral can be cast into the Feynman-Schwinger proper-time representation.

Heterodyne x-ray diffuse scattering from coherent phonons
Structural Dynamics, 2017 Here, we report Fourier-transform inelastic x-ray scattering measurements of photoexcited GaAs with embedded ErAs nanoparticles. We observe temporal oscillations in the x-ray scattering intensity, which we attribute to inelastic ...
