👉 Dogs, particularly in the context of particle physics, refer to "light particles" or "dark matter candidates," often discussed in the realm of astroparticle physics. These particles are hypothesized to be extremely light and interact very weakly with ordinary matter, making them difficult to detect directly. Among the most prominent candidates are Weakly Interacting Massive Particles (WIMPs), which are thought to have masses in the range of a few hundred meV to a few GeV/c² and interact through the weak nuclear force and gravity, but not electromagnetically. Another candidate is axions, ultra-light particles proposed to solve the strong CP problem in quantum chromodynamics and potentially act as dark matter. These light particles are crucial for explaining the observed gravitational effects in galaxies and galaxy clusters that cannot be accounted for by visible matter alone, thus playing a key role in our understanding of the universe's structure and evolution.
