Testing fundamental symmetries with Lambda(b) ---> Lambda-Vector decay

  title={Testing fundamental symmetries with Lambda(b) ---> Lambda-Vector decay},
  author={Olivier Leitner and Ziad Ajaltouni and Eric Conte},
  journal={arXiv: High Energy Physics - Phenomenology},
Putting together kinematical and dynamical analysis, a complete study of the decay channels $\Lambda_b \to {\Lambda} V(1^-)$, with $\Lambda \to p {\pi}^-$ and $V (J/\psi) \to {\ell}^+ {\ell}^-$ or $V ({\rho}^0) \to {\pi}^+ {\pi}^-,$ is performed. An intensive use of the helicity formalism is involved on the kinematical side, while on the dynamical side, Heavy Quark Effective Theory (HQET) is applied for an accurate determination of the hadronic matrix elements between the baryons $\Lambda_b…

Observations of $\Lambda_b^0 \to \Lambda K^+\pi^-$ and $\Lambda_b^0 \to \Lambda K^+K^-$ decays and searches for other $\Lambda_b^0$ and $\Xi_b^0$ decays to $\Lambda h^+h^{\prime -}$ final states
A search is performed for the charmless three-body decays of the Λ$_{b}^{0}$ and Ξ$_{b}^{0}$ baryons to the final states Λh$^{+}$ h′$^{−}$, where h$^{(}$′$^{)}$ = π or K. The analysis is based on a
