Zero energy scattering calculation in Euclidean space

Physics Letters B, 2016
We show that the Bethe–Salpeter equation for the scattering amplitude in the limit of zero incident energy can be transformed into a purely Euclidean form, as it is the case for the bound states.

Leading quantum gravitational corrections to QED [PDF]

, 2006
We consider the leading post-Newtonian and quantum corrections to the non-relativistic scattering amplitude of charged spin-1/2 fermions in the combined theory of general relativity and QED.

Analysis of the Lambda p Final State Interaction in the Reaction p+p->K^+(Lambda p)

, 2004
The missing mass spectrum measured in high resolution studies of the reaction pp -> K^+X is analyzed with respect to the strong final state interaction near the Lambda p production threshold.

Scattering on the supermembrane

Journal of High Energy Physics
We compute the one-loop 2 → 2 scattering amplitude of massless scalars on the world volume of an infinite D = 11 supermembrane quantized in the static gauge.

A NOTE ON COULOMB SCATTERING AMPLITUDE [PDF]

International Journal of Modern Physics A, 2007
The summation of the partial wave series for Coulomb scattering amplitude, fC(θ) is usually avoided because the series is oscillatorily and divergent. Instead, fC(θ) is generally obtained by solving the Schrödinger equation in parabolic cylindrical coordinates which is not a general method.

Exact 4-point Scattering Amplitude of the Superconformal Schrodinger Chern-Simons Theory

, 2012
We consider the non-relativistic superconformal U(N) X U(N) Chern-Simons theory with level (k,-k) possessing fourteen supersymmetries. We obtain an exact four-point scattering amplitude of the theory to all orders in 1/N and 1/k and prove that the ...

Analytic Amplitude Models for Forward Scattering [PDF]

, 2000
We report on fits of a large class of analytic amplitude models for forward scattering against the comprehensive data for all available reactions. To differentiate the goodness of the fits of many possible parametrizations to a large sample of data, we ...

On fine structure of strings: the universal correction to the Veneziano amplitude

Journal of High Energy Physics, 2018
We consider theories of weakly interacting higher spin particles in flat space-time. We focus on the four-point scattering amplitude at high energies and imaginary scattering angles. The leading asymptotic of the amplitude in this regime is universal and

Low energy proton-proton scattering in effective field theory

, 2007
Low energy proton-proton scattering is studied in pionless effective field theory. Employing the dimensional regularization and MS-bar and power divergence subtraction schemes for loop calculation, we calculate the scattering amplitude in 1S0 channel up ...
