Electromagnetic properties of the deuteron and the Bethe-Salpeter equation with one-boson exchange

Relativistic calculation of structure functions b1,2(x) of the deuteron

“…[14]. This amplitude is essentially just a different presentation of the amplitude obtained by Zuilhof and Tjon [12]. An important feature of the calculations is a numerical "inverse Wick rotation" of the amplitude.…”

“…This letter presents a study of the deuteron SFs b D 1,2 (x) within a covariant approach, based on the relativistic convolution formalism for the deep inelastic scattering [8,9,10,11] and the Bethe-Salpeter formalism for the deuteron bound state [12,13,14]. The issue of the sum rules is specially addressed.…”

Measurement of the deuteron elastic structure functions at large momentum transfers

“…In Equations (55) and (56), e σ (P, M) is the deuteron polarization vector with helicity M, P and P are the initial and final deuteron momenta and I ρσ μν is the infinitesimal generator of the Lorentz transformations [56]. In terms of F 1 , F 2 and G 1 , the charge, quadrupole and magnetic form factors are…”

O (4) Expansion of the Ladder Bethe-Salpeter Equation

“…Most efforts start with the reduction of the 4-dimensional integral equation into a 2-dimensional one by introducing a partial wave decomposition, thereby exploiting rotational symmetry [6,7]. The 2-dimensional integral equation is then solved by standard discretization methods.…”
