标题： Algebraic model of an oblate top

摘要： 我们考虑了一个三体系统的代数处理方法。特别是，我们发展了三个相同物体系统的形式主义，并讨论了将其应用于非奇特重子共振的实例，这些共振被解释为扁椭圆对称陀螺的振动和旋转激发。我们推导出一组基本形式因子的封闭表达式，这些因子出现在重子的电磁、强和弱耦合计算中。 显示英文摘要

摘要： We consider an algebraic treatment of a three-body system. In particular, we develop the formalism for a system of three identical objects and discuss an application to nonstrange baryon resonances which are interpreted as vibrational and rotational excitations of an oblate symmetric top. We derive closed expressions for a set of elementary form factors that appear in the calculation of both electromagnetic, strong and weak couplings of baryons.
