Updated measurement of decay-time-dependent CP asymmetries in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +910

A search for decay-time-dependent charge-parity ( $C P$ ) asymmetry in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays is performed at the LHCb experiment using proton-proton collision d…

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…

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 $2.3 \times 1 0^{6}$ $…

$χ_{c 1}$ and $χ_{c 2}$ resonance parameters with the decays $χ_{c 1, c 2} \to J / ψ μ^{+} μ^{-}$

LHCb collaboration, R. Aaij, B. Adeva +797

The decays $χ_{c 1} \to J / ψ μ^{+} μ^{-}$ and $χ_{c 2} \to J / ψ μ^{+} μ^{-}$ are observed and used to study the resonance parameters of the $χ_{c 1}$ and $χ_{c 2}$ mesons. The mass…

Measurement of $C P$ observables in $B^{\pm} \to D^{()} K^{\pm}$ and $B^{\pm} \to D^{()} π^{\pm}$ decays

LHCb collaboration, R. Aaij, B. Adeva +803

Measurements of $C P$ observables in $B^{\pm} \to D^{(*)} K^{\pm}$ and $B^{\pm} \to D^{(*)} π^{\pm}$ decays are presented, where $D^{(*)}$ indicates a neutral $D$ or $D^{*}$ m…

Dalitz plot analysis of Ds+ --> K+ K- pi+

P. del Amo Sanchez et al.

We perform a Dalitz plot analysis of about 100,000 Ds+ decays to K+ K- pi+ and measure the complex amplitudes of the intermediate resonances which contribute to this decay mode. We…
