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 the semileptonic decay $B^{+} \to p p μ^{+} ν_{μ}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +900

The Cabibbo-suppressed semileptonic decay $B^{+} \to p p μ^{+} ν_{μ}$ is observed for the first time using a sample of $pp$ collisions corresponding to an integrated luminosit…

Search for the doubly charmed baryon $Ξ_{cc}^{+}$

LHCb collaboration, R. Aaij, C. Abelán Beteta +905

A search for the doubly charmed baryon $Ξ_{cc}^{+}$ is performed through its decay to the $Λ_{c}^{+} K^{-} π^{+}$ final state, using proton-proton collision data collected with the LHCb de…

Precision measurement of the $Λ_{c}^{+}$ , $Ξ_{c}^{+}$ and $Ξ_{c}^{0}$ baryon lifetimes

LHCb collaboration, R. Aaij, C. Abellán Beteta +847

We report measurements of the lifetimes of the $Λ_{c}^{+}$ , $Ξ_{c}^{+}$ and $Ξ_{c}^{0}$ charm baryons using proton-proton collision data at center-of-mass energies of 7 and 8\tev, correspondin…

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…
