Physicists explore charged gravitinos as dark matter candidates

Charged gravitinos, ultra-heavy stable particles from supergravity theory, are now considered potential dark matter candidates. These particles, unlike previous candidates, possess electric charge but are extremely rare, making them difficult to detect. New detectors like JUNO and DUNE may offer a chance to observe their unique signals. The discovery of charged gravitinos could bridge the gap between particle physics and gravity, potentially offering the first experimental evidence for physics near the Planck scale.
