| 英文摘要 | In this paper, we study CP violation in Lambda(+)(c) BP and Lambda(+)(c) -> BV decays, where B, P and V denote a light spin-1/2 baryon, pseudoscalar and a vector meson respectively. In these processes the T odd CP violating triple-product (TP) correlations are examined. The genuine CP violating observables which are composed of the helicity mplitudes occurring in the angular distribution are constructed. Experimentally, by performing a full angular analysis it is shown how one may extract the helicity mplitudes and then obtain the TP asymmetries. We estimate the TP asymmetries in Lambda(+)(c) decays to be negligible in the Standard Model making these processes an xcellent place to look for new physics. Taking a two-Higgs doublet model, as an example of new physics, we show that large TP asymmetries are possible in these decays. Finally, we discuss how BES-III and super tau-charm experiments will be sensitive to these CP violating signals in Lambda(+)(c) decays. |
