Theoretical physicists propose using a centuries-old physics test to detect millicharged particles (mCPs), hypothetical particles that carry extremely small electric charges. These particles are predicted to interact very weakly with ordinary matter and electromagnetic fields, making them challenging to observe with conventional particle physics detection methods. The research suggests adapting classical physics experiments to search for these elusive particles.
Why it matters
If millicharged particles exist, they could help explain fundamental questions in physics, including the nature of dark matter and physics beyond the Standard Model. Detecting these particles would represent a significant breakthrough in our understanding of the universe's fundamental constituents.
Understand the Science
Theoretical physicists have long predicted the existence of millicharged particles (mCPs), hypothetical particles that carry a very small electric charge. These particles are expected to interact very weakly with ordinary matter and electromagnetic fields; hence, they would be difficult to detect in conventional particle physics experiments.
