Observation of new $Ω_{c}^{0}$ states decaying to the $Ξ_{c}^{+} K^{-}$ final state

LHCb collaboration

Two new excited states, $Ω_{c} (3185)^{0}$ and $Ω_{c} (3327)^{0}$ , are observed in the $Ξ_{c}^{+} K^{-}$ invariant-mass spectrum using proton-proton collision data collected by the LHCb experim…

Measurement of the ratios of branching fractions $R (D^{*})$ and $R (D^{0})$

LHCb Collaboration

The ratios of branching fractions $R (D^{*}) \equiv B (B ˉ \to D^{*} τ^{-} ν ˉ_{τ}) / B (B ˉ \to D^{*} μ^{-} ν ˉ_{μ})$ and $\mathcal{R}(D^{0})\equiv\mathca…

Measurement of the photon polarization in $Λ_{b} \to Λ γ$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994

The photon polarization in $b \to s γ$ transitions is measured for the first time in radiative b-baryon decays exploiting the unique spin structure of $Λ_{b} \to Λ γ$ decays. A data s…
