摘要：

Dark matter particles were suggested to have an electric charge smaller than the elementary charge unit e . The behavior of such a medium is similar to a collisionless plasma. In this paper, we set new stringent constraints on the charge and mass of the millicharged dark matter particle based on observational data on the Bullet X-ray Cluster.
