The accelerated expansion of the universe is due to the mutual repulsion of matter, and the decelerated expansion is due to the mutual attraction of matter. 
The particles in the standard model of particle physics are not unique, and there are other particles.
 to explain the acceleration or deceleration of the expansion of the universe on this basis, matter with different characteristics must be dominant in different periods, which can result in a strong repulsive force or attractive force. All particles in the standard model of particle physics can produce attractive gravitational force. However, the study of the rotation curve of the galaxy shows that there is a large amount of invisible matter in the galaxy which can produce a very powerful attractive gravity.
