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…

Observation of the leptonic decay $D^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +479

We report the first observation of $D^{+} \to τ^{+} ν_{τ}$ with a significance of $5.1 σ$ . We measure ${\cal B}(D^+\toτ^+ν_τ) = (1.20\pm0.24_{\text{stat.}}\pm0.12_{\text{syst.}})\times10^{-3…

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…

Complete measurement of $Λ$ electromagnetic form factors

M. Ablikim, M. N. Achasov, P. Adlarson +475

The exclusive process $e^{+} e^{-} \to Λ Λ ˉ$ , with $Λ \to p π^{-}$ and $Λ ˉ \to p ˉ π^{+}$ , has been studied at $s =$ 2.396 GeV for measurement of the $Λ$ electric and mag…

Search for lepton-universality violation in $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ decays

LHCb Collaboration, R. Aaij, C. Abellán Beteta +846

A measurement of the ratio of branching fractions of the decays $B^{+} \to K^{+} μ^{+} μ^{-}$ and $B^{+} \to K^{+} e^{+} e^{-}$ is presented. The proton-proton collision data used correspond to an integ…

Measurements of $C P$ asymmetries in charmless four-body $Λ_{b}$ and $Ξ_{b}^{0}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +841

A search for $C P$ violation in charmless four-body decays of $Λ_{b}$ and $Ξ_{b}^{0}$ baryons with a proton and three charged mesons in the final state is performed. To cancel out product…
