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)…
