Study of gravitational waves from phase transitions in three-component dark matter
Mohammad Hossein Rahimi Abkenar, Ahmad Mohamadnejad, Reza Sepahvand
This paper studies gravitational waves in a dark matter model composed of three types of particles with distinct spins, along with a scalar field that mediates interactions bet…
