The ForwArd Search ExpeRiment (FASER) will search for particles that might be produced parallel to the LHC’s beam line and may travel hundreds of metres without interacting before transforming into known and detectable particles, such as electrons and positrons.
Ongoing work for FASERν and successful tests promise timely installation of the new detector before the start of LHC Run 3. 
On March 5th the CERN Research Board approved the ForwArd Search ExpeRiment (FASER) designed to broaden the search for new physics at the LHC.
