Study of charmonium and charmonium-like contributions in $B^{+} \to J / ψ η K^{+}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +995

A study of $B^{+} \to J / ψ η K^{+}$ decays, followed by $J / ψ \to μ^{+} μ^{-}$ and $η \to γ γ$ , is performed using a dataset collected with the LHCb detector in proton-pro…

Prospects on searches for baryonic Dark Matter produced in $b$ -hadron decays at LHCb

Alexandre Brea Rodríguez, Veronika Chobanova, Xabier Cid Vidal +6

A model that can simultaneously explain Dark Matter relic density and the apparent matter anti-matter imbalance of the universe has been recently proposed. The model requires $b$ -h…

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

R. Aaij, C. Abellán Beteta, T. Ackernley +955

A search for the doubly charmed baryon $Ω_{cc}^{+}$ with the decay mode $Ω_{cc}^{+} \to Ξ_{c}^{+} K^{-} π^{+}$ is performed using proton-proton collision data at a centre-of-mas…

Search for $C P$ violation in $D_{(s)}^{+} \to h^{+} π^{0}$ and $D_{(s)}^{+} \to h^{+} η$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +957

Searches for $C P$ violation in the two-body decays $D_{(s)}^{+} \to h^{+} π^{0}$ and $D_{(s)}^{+} \to h^{+} η$ (where $h^{+}$ denotes a $π^{+}$ or $K^{+}$ meson) are p…

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…
