Towards Measurement of Antimatter Absorption Cross-Section: Deuteron Identification in ALICE

The ALICE detector on the Large Hadron Collider (LHC) at CERN, is optimized to study the products of heavy ion collisions in the LHC. One of the improvements under consideration for ALICE in the LHC Run III upgrade would enable ALICE to measure the inelastic cross-section of anti-deuterons produced in those collisions. In preparation of the measurement, a method of effectively identifying deuterons and anti-deuterons in the detector must be established, and a thorough simulation of the experiment must be conducted to enable effective data taking. We consider how data from the inner detectors can be used to improve anti-deuteron identification, and establishes the parameters necessary for initial simulations of the experiment. Specifically, we consider particle identification data from the Time Projection Chamber (TPD), Transition Radiation Detector (TRD), and Time of Flight Detector (TOF) in particle identification, and considers a simulation with six possible anti-particle absorbers.
