On the Dipole Picture in the Nonforward Direction
نویسندگان
چکیده
We calculate, for nonzero momentum transfer, the dipole formula for the high energy behaviour of elastic and quasielastic scattering of a virtual photon. We obtain an expression of the nonforward photon impact factor and of the nonforward photon wave function, and we give a physical interpretation.

In this paper, we investigated the effect of dipole-dipole interaction between the dust particles on the transverse oscillation of one dimensional dusty crystal. We used the Boltzmann distribution for the electrons and ions density and assumed that dust particles are negatively charged. The equation of motion for dust particles in this one dimensional chain was obtained. It is shown that the di...

In this paper, the interaction between an oscillating dipole moment and a Silver nanoparticle has been studied. Our calculations are based on Mie scattering theory and discrete dipole approximation(DDA) method.At first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using Mie scattering theory and then by exciting a dipole moment in theclose proximity of...
متن کاملNonforward Parton Densities and Soft Mechanism for Form Factors and Wide-Angle Compton Scattering in QCD
We argue that at moderately large momentum transfer −t ∼ 10 GeV , hadronic form factors and wide-angle Compton scattering amplitudes are dominated by mechanism corresponding to overlap of soft wave functions. We show that the soft contribution in both cases can be described in terms of the same universal nonforward parton densities (ND’s) F(x; t), which are the simplest hybrids of the usual par...
متن کاملTRANSLATING CULTURAL SIGNS IN CHILDREN’S PICTURE BOOKS
Every happening in one's life may be regarded by her/him as a leading phenomenon to other happenings. This leading phenomenon which can anticipate the subsequent happenings is called SIGN. Signs are unique for every group of human being and hence culture-specific. This is even true for every individual. Signs permeate in every aspect of universe. Among these fields, children's literature is stu...
متن کاملEffect of Induced Dipole-Induced Dipole Potential and the Size of Colliding Particles on Ion-Quadrupolar Molecule Collision Rate Constants
Classical trajectory (Monte Carlo) calculation is used to calculate collision rate constants of ion-quadrupolar molecule interactions for the H¯+C2H2 system. The method presented here takes into account the effect of the induced dipole-induced dipole potential on ion-quadrupolar molecule collision rate constants. It is also assumed that the colliding particles have a d...
