We present a new particle model that generalize for constant curvature space an infinite spin particle in flat space. The model is described by commuting Weyl spinor additional coordinates. It proved that such a model is consistent only in external gravitational field corresponding to the constant curvature spaces. Full set of the first-class constraints in the de Sitter and anti-de Sitter spaces is obtained.

常曲率空间中的无限（连续）自旋粒子


我们提出了一种新的粒子模型，该模型将恒定曲率空间推广为平坦空间中的无限自旋粒子。该模型通过换算 Weyl 旋量附加坐标来描述。证明了该模型仅在常曲率空间对应的外部引力场中是一致的。获得了德西特空间和反德西特空间中的全套第一类约束。
