Description
ALICE3 is proposed as the next-generation experiment for LHC Run 5 to address unresolved questions that cannot be answered fully with the present or currently planned detectors. Some key measurements will be the precise measurements of heavy-flavour probes, charmed exotic states, high-precision measurements of electromagnetic radiation, and chiral-symmetry restoration. To pursue this physics program, a concept of a novel detector with a high read-out rate, superb pointing resolution, and excellent tracking and particle identification over a large acceptance is being developed using advanced silicon detectors. It is being developed that concept of a high-resolution vertex tracker inside the beam pipe to achieve the best pointing resolution, which is surrounded by a silicon-pixel tracker covering about eight units of pseudo-rapidity. A combination of a time-of-flight system based on the silicon sensor and a Ring-Imaging Cherenkov detector is foreseen to achieve the particle identification performance required. Further detectors, such as an electromagnetic calorimeter, and a muon identifier, are being studied. This presentation will explain the detector concept and its physics reach and discuss the R&D challenges.
