Abstract:

Many popular extensions of the Standard Model predict the existence of particles that have a very small interaction probability with the ordinary particles. In several theoretical models these particles could be responsible for dark matter, and be the key to understand long-standing issues like the matter-antimatter asymmetry of the universe. Searching for long-lived particles is difficult, , since after production they would travel undetected, and they would only be observable if they convert back into visible particles, far from the interaction point. The LHC experiments have developed ingenious techniques to detect these particles, and several limits on their production now exist, despite the fact that the LHC experiments have not been designed for them. Other dedicated experiments have been proposed in the meantime, both at the LHC and in fixed target mode, and they will be also shortly presented.
