Query: Central exclusive production in the ALICE experiment at the LHC   The ALICE experiment at the Large Hadron Collider (LHC) at CERN consists of a
central barrel, a muon spectrometer and additional detectors for trigger and
event classification purposes. The low transverse momentum threshold of the
central barrel gives ALICE a unique opportunity to study the low mass sector of
central exclusive production at the LHC.
