Представлен алгоритм расчета форм-факторов мезонов процесса γγ* → P (qq) в модели, основанной на составной кварковой модели и точечной форме пуанкаре-инвариантной квантовой механике. Показано, что использование структурных функций конституентных кварков легкого сектора приводит к согласующемуся с экспериментальными данными поведению величины q² F p₀ (q²) процессов γγ* → π⁰, γγ* → η и γγ* → η` при больших переданных импульсах. По результатам работы предложена самосогласованная модель, удовлетворительно описывающая электрослабые распады псевдоскалярных мезонов легкого сектора. = The paper presents an algorithm for calculating the meson form factors of the γγ* → P (qq) process in a model based on the composite quark model and the point form of Poincaré-invariant quantum mechanics. It is shown that the use of structure functions of constituent quarks for the light sector leads to a behavior of the q² F p₀ (q²) value of the γγ* → π⁰, γγ* → η and γγ* → η`processes at large momentum transfers consistent with experimental data. A self-consistent model satisfactorily describing electroweak decays of pseudoscalar mesons of the light sector is proposed.
