Lambda_c的無輕子二體衰變

Study of the nonleptonic two-body decays of Lambda_c

指導教授 : 耿朝強

摘要


我們利用因子化法和SU(3)味對稱性兩種方法計算Lambda_c^+的無輕子的二體衰變。 對於因子化法,我們著重於Lambda_c^+ 到 p 和Lambda_c^ 到 Lambda這兩種轉換; 對於SU(3)味對稱性,我們則分析Lambda_c^+到重子八重態與介子九重態的衰變。 利用現有的實驗數據,我們藉以確定縮減振幅中的複數參數,並得到衰變比例。

We present two methods to obtain the branching ratios of the charmed baryon Lambda_c^+ nonleptonic two body decays: the Factorization and SU(3) flavor symmetry approaches. For the Factorization approach, we focus on the Lambda_c^+ to p and Lambda_c^+ to Lambda transition. While for the SU(3) flavor symmetry approach, we investigate the decays of Lambda_c^+ into an octet baryon and a nonet meson. We use the current experiment data to determine the complex parameters in the reduced amplitudes in order to obtain the branching ratios.
