使用 BESIII 探测器在 4.009 至 4.946 GeV 的质心能量处收集的数据样本，通过特定的电离能量损失信息研究了动量在 0.52−0.72 GeV/c 范围内的氘核的识别。使用飞行时间信息选择干净的氘核样品。对于所有数据样本，氘核识别效率均高于95%，数据与蒙特卡罗模拟之间的最大差异为%。这验证了基于特定电离能量损失的氘核识别方法的有效性，并为未来研究涉及BESIII最终态氘核的过程提供了有价值的信息。
The identification of deuterons with momenta in the range of 0.52−0.72 GeV/c is studied with specific ionization energy loss information using a data sample collected by the BESIII detector at center-of-mass energies between 4.009 and 4.946 GeV. Clean deuteron samples are selected using time of flight information. For all data samples, the deuteron identification efficiencies are higher than 95%, with a maximum difference of % between data and Monte Carlo simulation. This verifies the effectiveness of the deuteron identification method based on specific ionization energy loss and provides valuable information for future studies on processes involving deuterons in the final state at BESIII.
