Study of the $B^{0} \to ρ (770)^{0} K^{*} (892)^{0}$ decay with an amplitude analysis of $B^{0} \to (π^{+} π^{-}) (K^{+} π^{-})$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +840

An amplitude analysis of $B^{0} \to (π^{+} π^{-}) (K^{+} π^{-})$ decays is performed in the two-body invariant mass regions $300 < m (π^{+} π^{-}) < 1100$ MeV/ $c^{2}$ , accounting for the $ρ^{0}$ , $ω$ ,…

Measurement of the charm-mixing parameter $y_{C P}$

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

A measurement of the charm-mixing parameter $y_{C P}$ using $D^{0} \to K^{+} K^{-}$ , $D^{0} \to π^{+} π^{-}$ , and $D^{0} \to K^{-} π^{+}$ decays is reported. The $D^{0}$ mesons are required to originat…
