Charmed baryon decays in SU(3) symmetry

Jia, Cai-Ping; Wang, Di; Yu, Fu-Sheng

Abstract

In the recent years, fruitful results on charmed baryons are obtained by BESIII, Belle and LHCb. We in-vestigate the two-body non-leptonic decays of charmed baryons based on the exact flavor SU(3)symmetry without any other approximation. Hundreds of amplitude relations are clearly provided, and are classified according to the I-, U-and V-spin symmetries. Among them, some amplitude relations are tested by the experimental data, or used to predict the branching fractions based on the exact flavor symmetry without any other approximation. Some relations of K0S−K0Lasymmetries and CPasymmetries are obtained un-der the U-spin symmetry in the modes of charmed baryon decaying into neutral kaons. Besides, the U-spin breaking effect is explored in the +c→+K∗0and +c→pK∗0modes.
