Non-leptonic two-body decays of $\Lambda_b^0$ in light-front quark model
'Elsevier BV', 2021Co-Authors: Geng C. Q., Liu Chia-wei, Tsai Tien-hsuehAbstract:We study the non-leptonic two-body weak decays of $\Lambda_b^0 \to p M$ with $ M=(\pi^-,K^-)$ and $(\rho^-,K^{*-})$ in the light-front quark model under the generalized factorization ansatz. By considering the Fermi Statistic between quarks and determining spin-flavor structures in baryons, we calculate the branching ratios (${\cal B}$s) and CP-violating rate asymmetries ($\mathcal{A}_{CP}$s) in the decays. Explicitly, we find that ${\cal B}( \Lambda_b^0 \to p \pi^- ,pK^-)=(4.18\pm0.15\pm0.30, 5.76\pm0.88\pm0.23)\times10^{-6}$ and ${\mathcal{A}_{CP}}( \Lambda_b^0 \to p \pi^- ,\,pK^-)=(-3.60\pm0.14\pm0.14, 6.36\pm0.21\pm0.18)\%$ in comparison with the data of ${\cal B}( \Lambda_b^0 \to p \pi^- ,pK^-)=(4.5\pm0.8, 5.4\pm1.0)\times10^{-6}$ and ${\mathcal{A}_{CP}}( \Lambda_b^0 \to p \pi^- ,pK^-)=(-2.5\pm 2.9, -2.5\pm2.2)\%$ given by the Particle Data Group, respectively. We also predict that ${\cal B}( \Lambda_b^0 \to p \rho^-,pK^{*-} )=(12.13\pm3.27\pm0.91, 2.58\pm0.87\pm0.13)\times 10^{-6}$ and ${\mathcal{A}_{CP}}( \Lambda_b^0 \to p \rho^-,pK^{*-} )=(-3.32\pm0.00\pm0.14,19.25\pm0.00\pm0.80)\%$, which could be observed by the experiments at LHCb.Comment: 16 pages, 1 figure, accepted for publication in PLB. arXiv admin note: text overlap with arXiv:2002.1061

Semileptonic decays of $\Lambda_c^+$ in dynamical approaches
'American Physical Society (APS)', 2020Co-Authors: Geng C. Q., Liu Chia-wei, Lih Chong-chung, Tsai Tien-hsuehAbstract:We study the semileptonic decays of $\Lambda_c^+ \to \Lambda(n)\ell^+ \nu_{\ell}$ in two relativistic dynamical approaches of the light-front constituent quark model (LFCQM) and MIT bag model (MBM). By considering the Fermi Statistic between quarks and determining spin-flavor structures in baryons along with the helicity formalism in the two different dynamical models, we calculate the branching ratios (${\cal B}$s) and averaged asymmetry parameters ($\alpha$s) in the decays. Explicitly, we find that ${\cal B}( \Lambda_c^+ \to \Lambda e^+ \nu_{e})=(3.36\pm0.87,3.48)\%$ and ${\alpha}( \Lambda_c^+ \to \Lambda e^+ \nu_{e})=(-0.97\pm0.03,-0.83)$ in (LFCQM, MBM), in comparison with the data of ${\cal B}( \Lambda_c^+ \to \Lambda e^+ \nu_{e})=(3.6\pm0.4)\%$ and ${\alpha}( \Lambda_c^+ \to \Lambda e^+ \nu_{e})=-0.86\pm 0.04$ given by the Particle Data Group, respectively. We also predict that ${\cal B}( \Lambda_c^+ \to n e^+ \nu_{e})=(0.57\pm0.15, 3.6\pm1.5)\times 10^{-3}$ and ${\alpha}( \Lambda_c^+ \to n e^+ \nu_{e})=(-0.98\pm0.02,-0.96\pm0.04)$ in LFCQM with two different scenarios for the momentum distributions of quarks in the neutron, and ${\cal B}( \Lambda_c^+ \to n e^+ \nu_{e})= 0.279\times 10^{-2}$ and ${\alpha}( \Lambda_c^+ \to n e^+ \nu_{e})=-0.87$ in MBM, which could be tested by the ongoing experiments at BESIII, LHCb and BELLEII.Comment: 22 pages, 5 figures, revised version accepted by PR
