The FASER experiment is an LHC experiment located in a tunnel parallel to the LHC ring and is considerably smaller and low-budget compared to the titan LHC experiments such as ATLAS and CMS. The experiment seeks to detect new long-lived particles that have travelled half a kilometer from a LHC proton-proton collision site, escaping the major ATLAS experiment undetected. The only other proton collision “background” particles reaching FASER’s faraway location are muons and neutrinos. Evidence of a new particle, such as the hypothetical dark photon, may lead to answering our most fundamental questions of the Universe such as the origin of dark matter.
