Description
The aim of the paper is to remind that it is possible to study the properties of hadronic radial excitation of light mesons using the finite-energy QCD sum rules which are the QCD generalization of the method of the dual sum rules. It is noted that the experimental data, obtained in Protvino, are directly related to the QCD sum rule predictable characteristic of light mesons. This characteristic is the ratio of the axial and vector form factors of the radiative decay of charged pseudoscalar mesons π+ → e+νγ
Abstract (Russian)
Цель статьи - напомнить, что изучать свойства адронных возбуждений легких мезонов можно с помощью КХД правил сумм при конечных энергиях, которые являются КХД обобщением метода дуальных правил сумм. Отмечается, что экспериментальные данные, полученные в Протвино, непосредственно связаны с характеристикой легких мезонов, предсказуемой исходя из КХД правил сумм. Эта характеристика представляет собой отношение аксиального и векторного форм-факторов радиационного распада заряженных псевдоскалярных мезонов π+ → е+νγAdditional details
