Antitriplet charmed baryon decays with SU(3) flavor symmetry

First measurements of absolute branching fractions of the Ξc+ baryon at Belle

“…where the first uncertainties are statistical and the second systematic. The measured BðΞ þ c → Ξ − π þ π þ Þ value is consistent with the theoretical prediction within uncertainties [27]. The measured central value of BðΞ þ c → pK − π þ Þ is smaller than that of the theoretical predictions [23,28], perhaps indicating a large U-spin symmetry breaking effect in the singly-Cabibbo-suppressed charmed-baryon decays.…”

“…A few models have been developed to predict the decay rates of Ξ þ c . For example, the BðΞ þ c → Ξ − π þ π þ Þ has been predicted to be ð1.47 AE 0.84Þ% based on the SU(3) flavor symmetry [27]. Theory predicts BðΞ þ c → pK − π þ Þ to be ð2.2 AE 0.8Þ% based on the measured ratio BðΞ þ c → pK Ã0 Þ=BðΞ þ c → pK − π þ Þ and the U-spin symmetry that…”

U -spin sum rules for CP asymmetries of three-body charmed baryon decays

“…Three-body charmed baryon decays have been covered in the SU(3) F approach in Refs. [19,[58][59][60]. A general analysis of the New Physics (NP) sensitivity of different baryonic decay channels can be found in Ref.…”

Sum rules for CP asymmetries of charmed baryon decays in the $$SU(3)_F$$ limit

“…Recent studies for charmed baryon decays in the SU (3) irreducible representation amplitude (IRA) approach [29,40,42,54,60,61,64,68,70,71,74,81] do not analyze C P asymmetries because they ignore the two 3-dimensional irreducible representations and make the approximation of V * cs V us −V * cd V ud in the 15-and 6-dimensional irreducible representations, leading to the vanishing of the contributions proportional to λ b = V * cb V ub . If the contributions proportional to λ b are included, the SU (3) irreducible representation amplitude approach then can be used to investigate C P asymmetries in the charmed baryon decays.…”
