We perform a search for near-threshold $Xi_b^0$ resonances decaying to $Xi_b^- pi^+$ in a sample of proton-proton collision data corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by the LHCb experiment. We observe one resonant state, with the following properties: begin{eqnarray*} m(Xi_b^{*0}) - m(Xi_b^-) - m(pi^+) &=& 15.727 pm 0.068 , (mathrm{stat}) pm 0.023 , (mathrm{syst}) , mathrm{MeV}/c^2, Gamma(Xi_b^{*0}) &=& 0.90 pm 0.16 , (mathrm{stat}) pm 0.08 , (mathrm{syst}) , mathrm{MeV} . end{eqnarray*} This confirms the previous observation by the CMS collaboration. The state is consistent with the $J^P=3/2^+$ $Xi_b^{*0}$ resonance expected in the quark model. This is the most precise determination of the mass and the first measurement of the natural width of this state. We have also measured the ratio begin{align*} frac{sigma(pp to Xi_b^{*0} X){cal{B}}(Xi_b^{*0} to Xi_b^- pi^+)}{sigma(pp to Xi_b^- X)} = 0.28 pm 0.03 , (mathrm{stat}) pm 0.01 , (mathrm{syst}) . end{align*}
Bottom baryons decaying to a J/psi meson and a hyperon are reconstructed using 1.0 fb^{-1} of data collected in 2011 with the LHCb detector. Significant Lambda_b^0 rightarrow J/psi Lambda, Xi_b^-rightarrow J/psi Xi^- and Omega_b^- rightarrow J/psi Om
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 $Xi_b^0toXi_c^+pi^-$, $Xi_c^+to pK^-pi^+$ signal decays are reconstructed. Fr
Using a data sample of pp collisions corresponding to an integrated luminosity of $3~ rm fb^{-1}$, the $Xi_b^-$ and $Omega_b^-$ baryons are reconstructed in the $Xi_b^- rightarrow J/psi Xi^-$ and $Omega_b^- rightarrow J/psi Omega^-$ decay modes and t
We report on measurements of the mass and lifetime of the Xi_b^- baryon using about 1800 Xi_b^- decays reconstructed in a proton-proton collision data set corresponding to an integrated luminosity of 3.0 fb^{-1} collected by the LHCb experiment. The
A search for baryon-number-violating $Xi_b^0$ oscillations is performed with a sample of $pp$ collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb$^{-1}$. The baryon number at the moment of production is i
