强子形状因子的Boost修正波函数

Hadron Form Factors with the Boost-Corrected Wave Functions

Yu. A. Simonov

摘要:

强子形状因子的计算使用洛伦兹收缩波函数,确定在任意动力学计划与瞬时相互作用。结果表明,形状因子的大$Q$渐近性由收缩系数$C_m(Q^2) = \frac{m}{\sqrt(m^2+ Q^2/4)}$定义,其中$m$是介子质量,并弱依赖于所用的相互作用.得到的形状因子$F_π$和$F_K$与晶格和实验数据吻合良好。强子衰变和散射的动力学的重要后果进行了简短的讨论。

英文摘要:

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 $F_π$ 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.
