We introduce and study a model designed to simultaneously shed light on the mysteries connected with Baryogenesis, Dark Matter and Dark Energy. The model describes a self-interacting complex axion field whose imaginary part, a pseudo-scalar axion, couples to the instanton density of gauge fields including the hypercharge field. This coupling may give rise to baryogenesis in the early universe. After tracing out the gauge and matter degrees of freedom, a non-trivial effective potential for the angular component of the axion field is obtained. It is proposed that oscillations of this component around a minimum of its effective potential can be interpreted as Dark Matter. The absolute value of the axion field rolls slowly towards 0. At late times, it can give rise to Dark Energy.

我们介绍并研究了一个模型，旨在同时阐明与重核发生、暗物质和暗能量相关的奥秘。该模型描述了一个自相互作用的复杂轴子场，其虚部（伪标量轴子）与包括超电荷场在内的规范场的瞬子密度耦合。这种耦合可能会导致早期宇宙中的重子发生。在描出规范和物质自由度之后，得到了轴场角分量的非平凡有效势。有人提出，该分量在其有效电位最小值附近的振荡可以解释为暗物质。轴子场的绝对值缓慢地向0滚动。在后期，它可以产生暗能量。
