FASER

Taking a closer look at LHC

(Taken from FASER-CERN)

FASER (Forward Search Experiment), is designed to search for light and extremely weakly interacting particles. The existence of such new particles is predicted by many models beyond the Standard Model that attempt to solve some of the biggest puzzles in physics, such as the nature of dark matter, the origin of neutrino masses, and the imbalance between matter and antimatter in the present-day universe.

The four main LHC detectors, ALICE, ATLAS, CMS and LHCb, are not suited to detect signals from light and weakly interacting particles produced parallel to the proton beamline, because they have holes along the beamline to let the proton beams through. Located along the beam trajectory, 480 metres downstream of the ATLAS detector, FASER is ideally positioned to detect the particles into which such light and weakly interacting particles will decay.

FASER also comprise a subdetector called FASERν, which is specifically designed to detect neutrinos. No neutrino produced at a particle collider has ever been detected, despite colliders producing them in huge numbers and at high energies. As a result, neutrino interactions at these high energies have not yet been studied in detail. The FASERν">ν detector is a 25\cm×25\cm×1.35\m">25\cm×25\cm×1.35\m emulsion detector, consisting of 1000 layers of emulsion films interleaved with 1-mm-thick tungsten plates, with a total tungsten target mass of 1.2 tons. It is located at the front of the FASER main detector in a narrow trench being excavated specifically to house it.
