What signature do physicists look for when using particle accelerators like the LHC to search for dark matter production?
Answer
Missing energy in collision debris.
Since a dark matter particle produced in a collider would not interact with the detector, its presence is inferred by measuring an imbalance where the total energy of the outgoing debris is less than the initial collision energy, indicating an unseen particle carried the rest away.
