Displaced vertices refer to the location of a particle decay event occurring at a distance away from the original primary collision point in high-energy physics experiments. These events are typically studied in experiments such as at the Large Hadron Collider (LHC), where particles with short lifetimes can travel a measurable distance before decaying into other particles. By studying displaced vertices, researchers can gain insights into properties of exotic particles, such as their masses, lifetimes, and interactions, which may not be directly observable at the primary collision point. Studying displaced vertices can also help in the search for new physics beyond the Standard Model of particle physics.
