Three-body charmed baryon Decays with SU(3) flavor symmetry

C. Q. Geng, Y. K. Hsiao, Chia-Wei Liu +1

We study the three-body anti-triplet $B_{c} \to B_{n} M M^{'}$ decays with the $S U (3)$ flavor ( $S U (3)_{f}$ ) symmetry, where $B_{c}$ denotes the charmed baryon anti-triplet of $…

Non-leptonic two-body weak decays of $Λ_{c} (2286)$

C. Q. Geng, Y. K. Hsiao, Yu-Heng Lin +1

We study the non-leptonic two-body weak decays of $Λ_{c}^{+} (2286) \to B_{n} M$ with $B_{n}$ ( $M$ ) representing as the baryon (meson) states. Based on the $S U (3)$ flavor symmetr…

Branching fractions of $B_{(c)}$ decays involving $J / ψ$ and $X (3872)$

Y. K. Hsiao, C. Q. Geng

We study two-body $B_{(c)} \to M_{c} (π, K)$ and semileptonic $B_{c} \to M_{c} ℓ^{-} ν ˉ_{ℓ}$ decays with $M_{c} = (J / ψ, X_{c}^{0})$ , where $X_{c}^{0} \equiv X^{0} (3872)$ is regarded as the tetraquark…

Exploring the simplest purely baryonic decay processes

C. Q. Geng, Y. K. Hsiao, Eduardo Rodrigues

Though not considered in general, purely baryonic decays could shed light on the puzzle of the baryon number asymmetry in the universe by means of a better understanding of the bar…

Search for $X Y Z$ states in $Λ_{b}$ decays at the LHCb

Y. K. Hsiao, C. Q. Geng

We consider $X (3872)$ and $Y (4140)$ as the vector tetraquark states of $X_{c}^{0} \equiv c c ˉ u u ˉ (d d ˉ)$ and $c c ˉ s s ˉ$ , respectively. By connecting $Λ_{b} \to X_{c}^{0} Λ$ to…

Fragmentation fractions of two-body b-baryon decays

Y. K. Hsiao, P. Y. Lin, L. W. Luo +1

We study the fragmentation fractions $(f_{B_{b}})$ of the $b$ -quark to b-baryons ( $B_{b}$ ). By the assumption of $f_{Λ_{b}} / (f_{u} + f_{d}) = 0.25 \pm 0.15$ in accordance with the mea…
