The absence of any significant signal for Physics Beyond the Standard Model from the experiments at the LHC so far has led to expanding the search space for new exotic particles and effects. One direction that has recently drawn increased attention is the search for new long-lived particles, such as monopoles, dark photons, weakly interacting neutral particles, heavy stable charge particles and so on. Present LHC experiments have some coverage for such particles but are not be able to cover all the possible phase space. New small-scale experiments are proposed to complement these searches at the LHC, such as MilliQan, Faser, Mathusla, Codex-b, Al3x, in a similar fashion as the already running MoEDAL monopole search experiment. This talk will introduce these recent ideas and physics search targets of these new experimental proposals.
