Description |
Long-lived particles are predicted by many extensions of the standard model. Particles that fly a measurable distance before decaying inside the detector produce a clear experimental signature that provides very efficient background suppression. In this talk I will describe recent work in this area. This will include a search for a heavy neutral lepton (HNL) at ATLAS, an HNL search at Belle that covers a different mass range, and several proposed searches of long lived particles in additional scenarios.
