Higher twist corrections to doubly-charmed baryonic B decays
Abstract Baryonic two-body B mesons decays have been measured experimentally for some time, which provides an excellent ground for studying the QCD of baryonic B decays. In this work, we investigate the two-body doubly-charmed baryonic B decays in the perturbative QCD (PQCD) approach including highe...

| description | Abstract Baryonic two-body B mesons decays have been measured experimentally for some time, which provides an excellent ground for studying the QCD of baryonic B decays. In this work, we investigate the two-body doubly-charmed baryonic B decays in the perturbative QCD (PQCD) approach including higher twist contributions to the light-cone distribution amplitudes (LCDAs). The charmed baryon LCDAs are included up to the twist four and the effect of the subleading component of the B meson LCDAs is studied for details. With the inclusion of these higher-power contributions, the PQCD results on rates can explain the current experimental data well. Moreover, we note that the SU(3) symmetry breaking is important in the concerned processes and play an essential role in understanding the measurements of B B ¯ 0 → Λ c + Λ ¯ c − $$ \mathcal{B}\left({\overline{B}}^0\to {\Lambda}_c^{+}{\overline{\Lambda}}_c^{-}\right) $$ and B B − → Ξ c 0 Λ ¯ c − $$ \mathcal{B}\left({B}^{-}\to {\Xi}_c^0{\overline{\Lambda}}_c^{-}\right) $$ . We also evaluate the angular asymmetries for the first time, which have neither been measured experimentally nor calculated theoretically. All these predictions can be tested in future. |
