Abstract: In spite of making much effort in dark matter (DM) searches, its discovery has not been reported yet. Considering the current situation, the wide coverage of the DM parameter space is getting more important. For WIMP searches, the next frontier would be the TeV scale. Indirect DM searches with gamma rays give us a chance to search for heavy DM, which is difficult to reach with other ways by the limitation of beam energies or lack of statistics. This seminar will present the latest results on TeV-scale DM searches with ground gamma-ray telescopes such as MAGIC and CTA, in particular. Not only WIMP scenario. there is also an alternative, which is called "WIMPless" miracle, assuming the existence of Long-Lived Particles. In this seminar, we would like to discuss a new experiment at the LHC, called the FASER experiment. FASER makes use of the LHC forward beam and is sensitive to long-lived particles with masses in the MeV-GeV range. It has been taking data from the beginning of Run3, which started on July 2022. This seminar will present the latest status of the FASER experiment.
