Взаимодействие кварков описывается КХД-модифицированным корнельским потенциалом с введенной зависимостью от расстояния величиной сильной связи αS(r). Предложено уравнение движения для двух взаимодействующих бесспиновых частиц в системе центра инерции, получены два асимптотических решения этого уравнения для больших и малых расстояний. На этой основе предложена комплексная интерполяционная массовая формула для кварк-антикварковых состояний. Вычисленные в рамках модели спектры масс ρ и D±* мезонов оказываются в хорошем согласии с экспериментальными значениями.</p><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>Mesons as bound states of quarks with coordinate-dependent mass are modeled. The interaction of quarks is described by the QCD modiﬁed Cornell potential with a strong position-dependent coupling αS(r). The equation of motion for the system of two interacting spinless particles in the center-of-mass frame is suggested. Two asymptotic solutions of this equation for large and small distances are obtained. The mass formula is derived for quark-antiquark bound states on this basis. The mass spectra of the ρ and D±* calculated in the framework of the model are in a good agreement with experimental data. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>мезон</kwd><kwd>связанное состояние</kwd><kwd>потенциал</kwd><kwd>кварковая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>meson</kwd><kwd>bound state</kwd><kwd>potential</kwd><kwd>quark model</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Коллинз, П.
