Factorization for short distance hadron-hadron scattering
Nuclear Physics B, 1985 Abstract We show that factorization holds at leading twist in the Drell-Yan cross section dσ/dQ2dy and related inclusive hadron-hadron cross sections. We review the heuristic arguments for factorization, as well as the difficulties which must be overcome in a proof.

Long-range potential scattering: Converting long-range potential to short-range potential by tortoise coordinate [PDF]
J. Math. Phys. 62, 122102 (2021), 2018 Inspired by general relativity, we suggest an approach for long-range potential scattering. In scattering theory, there is a general theory for short-range potential scattering, but there is no general theory for long-range potential scattering. This is because the scattering boundary conditions for all short-range potentials are the same, but for ...

, 2011 The behavior of the hadron scattering amplitude determined by the gravitation interaction of hadron at high energies with impact of the KK-modes in d-brane models of gravity is examined. The possible periodic structure of the scattering amplitude and its

Isospin quantum distances in hadron-hadron scattering
Physics Letters B, 1996 Abstract In this paper, the quantum distances between two isospin channels, in the Hilbert space of the hadron-hadron scattering amplitudes, are introduced. These isospin quantum distances, as well as their isospin bounds, are expressed in terms of the channel cross sections and polarisation parameters.

Estimating the size of the scatterer [PDF]
, 2019 Formula for the size of the scatterer is derived explicitly in terms of the scattering amplitude corresponding to this scatterer. By the scatterer either a bounded obstacle $D$ or the support of the compactly supported potential is ...

Spin-orbit scattering visualized in quasiparticle interference [PDF]
Phys. Rev. B 95, 115307 (2017), 2017 In the presence of spin-orbit coupling, electron scattering off impurities depends on both spin and orbital angular momentum of electrons -- spin-orbit scattering. Although some transport properties are subject to spin-orbit scattering, experimental techniques directly accessible to this effect are limited.

Hadron-Hadron Interactions from Imaginary-time Nambu-Bethe-Salpeter Wave Function on the Lattice [PDF]
, 2012 Imaginary-time Nambu-Bethe-Salpeter (NBS) wave function is introduced to extend our previous approach for hadron-hadron interactions on the lattice. Scattering states of hadrons with different energies encoded in the NBS wave-function are utilized to ...

About the vacuum structure in QCD and hadron-hadron scattering [PDF]
Zeitschrift für Physik C Particles and Fields, 1985 We comment on an unconventional factorization scheme which has been recently proposed by Nachtmann and Reiter. These authors propose to take into account the influence of the vacuum structure of QCD by including a correlation in spin and colour for the partons that initiate a hard scattering process.

Nonuniversality of the interference quantum correction to conductivity beyond the diffusion regime [PDF]
Phys. Rev. B 73, 233301 (2006), 2006 Results of numerical simulation of the weak localization in two-dimensional systems in wide range of magnetic filed are presented. Three cases are analyzed: (i) the isotropic scattering and randomly distributed scatterers; (ii) the anisotropic scattering and randomly distributed scatterers; (iii) the isotropic scattering and the correlated distribution
