Δ-algebra and scattering amplitudes [PDF]
Journal of High Energy Physics, 2019 Abstract In this paper we study an algebra that naturally combines two familiar operations in scattering amplitudes: computations of volumes of polytopes using triangulations and constructions of canonical forms from products of smaller ones.

The High Energy Behavior of Mellin Amplitudes [PDF]
, 2019 In any consistent massive quantum field theory there are well-known bounds on scattering amplitudes at high energies. In conformal field theory there is no scattering amplitude, but the Mellin amplitude is a well-defined object analogous to the ...

An Analysis of the New LHC Data through the Dispersion Relations [PDF]
, 2016 We analyse the tension between the (indirect) measurements of the total cross section, and show the impact of various assumptions on the extraction of the parameters from the elastic scattering amplitude, with a special attention to the total cross ...

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.

High-energy quark-quark scattering and the eikonal approximation [PDF]
, 1997 The high-energy quark-quark scattering amplitude is calculated first in the case of scalar QCD, using Fradkin's approach to derive the scalar quark propagator in an external gluon field and computing it in the eikonal approximation.

Scattering amplitude from Bethe-Salpeter wave function inside the interaction range [PDF]
, 2018 We propose a method to calculate scattering amplitudes using the Bethe-Salpeter wave function inside the interaction range on the lattice. For an exploratory study of this method, we evaluate a scattering length of $I=2$ S-wave two pions by the use of ...

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 ...

Rigorous analysis of extremely asymmetrical scattering of electromagnetic waves in slanted periodic gratings [PDF]
, 2001 Extremely asymmetrical scattering (EAS) is a new type of Bragg scattering in thick, slanted, periodic gratings. It is realised when the scattered wave propagates parallel to the front boundary of the grating.

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.
