Nonleptonic decays of ${\Xi }_{cc}\to {\Xi }_c\pi$ with ${\Xi }_c-{\Xi }_c^{\prime }$ mixing

Chia-Wei Liu, Chao-Qiang Geng

Aiming on testing the ${\Xi }_c-{\Xi }_c^{\prime }$ mixing, we study the decays of ${\Xi }_{cc}\to {\Xi }_c\pi$ with ${\Xi }_{cc}=({\Xi }_{cc}^{++},{\Xi }_{cc}^{+})$, ${\Xi }_c=({\Xi }_c^{(\prime )+},{\Xi }_c^{(\prime )0})$ and $π= (π^+…
