Pseudo Nambu Goldstone bosons or axionlike particles (ALPs) can be light remnants of a heavy new physics sector. The UV structure of this sector determines the coupling structure of the ALPs. Light ALPs are strongly constrained from beam-dump searches and astrophysical observables and for ALPs with masses close to the electroweak scale can be discovered with resonance searches. I will discuss different techniques to discover ALPs in the intermediate mass range with a special focus on long-lived ALPs. A particularly interesting model are ALPs with an additional Z2 symmetry that can be a Dark Matter candidate even for sizable couplings. In this context I will present a new strategy to discover this type of Dark Matter at the LHC .
