Electromagnetic Form Factors of Quarks and Quark-Hadron Scattering

概要

Electromagnetic form factors of hadrons are considered by both quark form factors and a quark-hadron scattering amplitude. The quark form factors satisfy the scaling law at large -q^2, i.e., g_M(q^2)/g_E(q^2)=μ, and the effect of these form factors is studied in deep inelastic electron scattering. The quark-hadron scattering amplitude is approximated by the exchange of a quark or diquark, and their trajectories have intercepts of α_q(0)〜1/2 and α_d(0)〜-1. Furthermore, _νW_2^<eP>→_<χ→>1/4 is explained by the quantum number dependence of diquark trajectories.
