Isospin amplitudes in $Λ_{b}^{0} \to J / ψ Λ (Σ^{0})$ and $Ξ_{b}^{0} \to J / ψ Ξ^{0} (Λ)$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +902

Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions, and allow searches for physics beyond the Standard Model. We…

Observation of a narrow pentaquark state, $P_{c} (4312)^{+}$ , and of two-peak structure of the $P_{c} (4450)^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +866

A narrow pentaquark state, $P_{c} (4312)^{+}$ , decaying to $J / ψ p$ is discovered with a statistical significance of $7.3 σ$ in a data sample of $Λ_{b}^{0} \to J / ψ p K^{-}$ decays which is an or…

Amplitude analysis of the $B_{(s)} \to K^{* 0} K^{* 0}$ decays and measurement of the branching fraction of the $B \to K^{* 0} K^{* 0}$ decay

LHCb Collaboration, R. Aaij, C. Abellán Beteta +844

The $B^{0} \to K^{* 0} K^{* 0}$ and $B_{s}^{0} \to K^{* 0} K^{* 0}$ decays are studied using proton-proton collision data corresponding to an integrated luminosity of 3…

Measurement of the mass difference between neutral charm-meson eigenstates

LHCb Collaboration, R. Aaij, C. Abellán Beteta +842

We report a measurement of the mass difference between neutral charm-meson eigenstates using a novel approach that enhances sensitivity to this parameter. We use $2.3 \times 1 0^{6}$ $…
