Abstract

Hadron form factors are calculated using the Lorentz-contracted wave functions, determined in the arbitrary dynamical scheme with the instantaneous interaction. It is shown that the large \(Q\) asymptotics of the form factors is defined by the contraction coefficient \(C_{m}(Q^{2})=\frac{m}{\sqrt{(}m^{2}+Q^{2}/4)}\), where \(m\) is the meson mass, and weakly depends on the interaction used. The resulting form factors \(F_{\pi}\) and \(F_{K}\) are obtained in good agreement with the lattice and experimental data. Important consequences for the dynamics of hadron decays and scattering are shortly discussed.

具有Boost-Corrected Wave函数的强子形状因数

摘要

使用洛伦兹收缩波函数计算强子形状因数，该函数是在具有瞬时相互作用的任意动力学方案中确定的。结果表明，形状因子的大\（Q \）渐近性由收缩系数\（C_ {m}（Q ^ {2}）= \ frac {m} {\ sqrt {（} m ^ { 2} + Q ^ {2} / 4）} \），其中\（m \）是介子质量，并且弱依赖于所使用的相互作用。得到的形状因子\（F _ {\ pi} \）和\（F_ {K} \）与晶格和实验数据非常吻合。简短讨论了强子衰变和散射动力学的重要后果。
