Heavy Stable Charged Particles

HSCP limits  Heavy stable (or quasi-stable) charged particles (HSCPs) appear in various extensions of the standard model. If the lifetime of an HSCP produced at the Large Hadron Collider (LHC) is longer than a few nanoseconds, the particle will travel over distances that are comparable or larger than the size of a typical particle detector like the CMS experiment.
These HSCPs will be directly observable through the distinctive signature of a high momentum (p) particle with an anomalously large rate of energy loss through ionization (dE/dx) and delayed Time of Flight (ToF). The Naples group participates in the search of this particles studying the trigger for HSCPs and developing new techniques for the search of this exotica signal.
