| الوصف: | Minicharged particles (mCPs), hypothetical free particles with tiny electric charges below the elementary charge, $e$, offer a valuable probe of dark sectors and fundamental physics through several clear experimental signatures. Various models of physics beyond the Standard Model predict the existence of such particles, which could help elucidate the ongoing mysteries regarding electric charge quantization and the nature of dark matter. Moreover, a hypothetical scenario involving a small minicharged subcomponent of dark matter has recently been demonstrated as a viable explanation of the anomaly in the 21 cm hydrogen absorption signal reported by the EDGES collaboration. Although several decades of indirect observations and direct experimental searches for mCPs at particle accelerators have led to severe constraints, a substantial window of the mCP mass$\unicode{x2013}$mixing parameter space remains unexplored at the energy frontier accessible to current state-of-the-art accelerators, such as the Large Hadron Collider (LHC). Consequently, mCPs have remained topical over the years, and new experimental searches at accelerators have been gaining interest. In this article, we review the theoretical frameworks in which mCPs emerge and their phenomenological implications, the current direct and indirect constraints on mCPs, and the present state of the ongoing and upcoming searches for mCPs at particle accelerators. Additionally, we present the results of an updated study of the projected sensitivity of the recently approved (and relocated) Phase-1 detector of the MoEDAL's Apparatus for Penetrating Particles (MAPP) experiment to Drell$\unicode{x2013}$Yan pair-produced mCPs at the LHC's Run 3 and the future High-Luminosity LHC. Comment: 20 pages, 5 figures.
