摘要:

利用能量范围为0.90 - 1.08GeV的标记光子束,成功地进行了液态氘靶奇异光生过程的实验研究。实验的目的是测量中性K介子和氘上的λ粒子的产生。通过在中性K介子谱仪2中测量它们的衰变带电粒子来验证光生粒子的产生。通过选择其中识别出两个或更多个粒子轨迹的事件来实现重建的不变质量分布。初步结果如下。

英文摘要:

An experiment designed to investigate the strangeness photoproduction process using a tagged photon beam in the energy range of 0.90 -1.08 GeV incident on a liquid deuterium target was successfully performed. The purpose of the experiment was to measure the production of neutral kaons and the lambda particles on a deuteron. The generation of photo produced particles was verified by the measurement of their decayed charged particles in the Neutral Kaon Spectrometer 2. The reconstructed invariant mass distributions were achieved by selecting events where two or more particles tracks were identified. Preliminary results are presented here.
