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…

Determination of $∣ V_{u b} ∣$ from exclusive baryonic $B$ decays

Y. K. Hsiao, C. Q. Geng

We use the exclusive baryonic $B$ decays to determine the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V_{u b}$ . From the relation $|V_{ub}|^2/|V_{cb}|^2=({\cal B}_π/{\cal B}_D){…

Pentaquarks from intrinsic charms in $Λ_{b}$ decays

Y. K. Hsiao, C. Q. Geng

We study the three-body $Λ_{b}$ decays of $Λ_{b} \to J / ψ pM$ with $M = K^{-}$ and $π^{-}$ . The two new states $P_{c 1} \equiv P_{c} (4380)^{+}$ and ${\cal P}_{c2}\equiv {\cal P}_c(4450)…

Violation of PCAC and two-body baryonic $B$ and $D_{s}$ decays

Y. K. Hsiao, C. Q. Geng

We study the two-body baryonic $B$ and $D_{s}$ decays based on the annihilation mechanism without the partial conservation of axial-vector current (PCAC) at the GeV scale. We demonst…

Identifying Glueball at 3.02 GeV in Baryonic $B$ Decays

Y. K. Hsiao, C. Q. Geng

We examine the nature of the unknown enhancement around 3 GeV observed by the BABAR collaboration in the $m_{p p ˉ}$ spectrum of the $B ˉ^{0} \to p p ˉ D^{0}$ decay. Suspecting t…

Experimental study of psi' decays to K+K- pi^0 and K+K- eta

M. Ablikim, M. N. Achasov, D. J. Ambrose +353

Using $(106 \pm 4) \times 1 0^{6}$ $\psip$ events accumulated with the BESIII detector at the BEPCII $e^{+} e^{-}$ collider, we present measurements of the branching fractions for psi' decays…

C. Q. Geng, Y. K. Hsiao

We examine the three-body baryonic $B ˉ \to B B ˉ^{'} V$ decays with $V$ vector mesons in the standard model. We can simultaneously explain the recent experimental data on th…
