摘要：
我们引入了一个新的动力学群，其动量空间上的共伴随作用考虑了纯几何基础上的物质-反物质对称性。根据这种描述，在物质-反物质对称下，能量和自旋是不变的。我们记得庞加莱群的反时分量，支配质点的相对论运动，产生负能量粒子。受到萨哈罗夫的启发，两个孪生宇宙的模型解决了稳定性问题。正能量粒子和负能量粒子的运动有两种不同的折叠。该模型被扩展到带电粒子。因此，物质-反物质二元性在两个宇宙中都成立。
英文摘要：
We introduce a new dynamical group whose coadjoint action on its momentum space takes account of matter-antimatter symmetry on pure geometrical grounds. According to this description the energy and the spin are unchanged under matter-antimatter symmetry. We recall that the antichron components of the Poincaré group, ruling relativistic motions of a mass-point particle, generate negative energy particles. The model with two twin universes, inspired by Sakharov's one, solves the stability issue. Positive and negative energy particles motions hold in two distinct folds. The model is extended to charged particles. As a result, the matter-antimatter duality holds in both universes.
