The recent status of the FASER detector

FASER, the ForwArd Search ExpeRiment, is an experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in the high-energy collisions at the LHC and then decay to visible particles in FASER, which is placed 480 m downstream of the ATLAS interaction point. FASER, also includes a sub-detector, FASER$\nu$, designed to detect neutrino’s produced in the LHC collisions and to study their properties. In this paper, we introduce each component of the FASER detector that has been installed into the LHC during Long Shutdown 2 and the current status of the commissioning.
