Observation of $Λ_{b}^{0} \to D^{+} p π^{-} π^{-}$ and $Λ_{b}^{0} \to D^{*+} p π^{-} π^{-}$ decays

R. Aaij, A. S. W. Abdelmotteleb, C. Abellán Beteta +995

The multihadron decays $Λ_{b}^{0} \to D^{+} p π^{-} π^{-}$ and $Λ_{b}^{0} \to D^{*+} p π^{-} π^{-}$ are observed in data corresponding to an integrated luminosity of 3fb $^{- 1}$ , collecte…

Observation of a $Λ_{b}^{0} - Λ_{b}^{0}$ production asymmetry in proton-proton collisions at $s = 7 and 8 TeV$

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +973

This article presents differential measurements of the asymmetry between $Λ_{b}^{0}$ and $Λ_{b}^{0}$ baryon production rates in proton-proton collisions at centre-of-mass energies…

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 $2.3 \times 1 0^{6}$ $…

Dalitz plot analysis of the $D^{+} \to K^{-} K^{+} K^{+}$ decay

LHCb Collaboration, R. Aaij, B. Adeva +98

The resonant structure of the doubly Cabibbo-suppressed decay $D^{+} \to K^{-} K^{+} K^{+}$ is studied for the first time. The measurement is based on a sample of pp-collision data, collecte…

Study of J/psi->eta phi pi+pi- at BESIII

M. Ablikim, M. N. Achasov, X. C. Ai +402

Based on a sample of $2.25 \times 1 0^{8} J / ψ$ events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay $J / ψ \to η ϕ π^{+} π^{-}$ . The…

Precision measurement of the $D^{* 0}$ decay branching fractions

M. Ablikim, M. N. Achasov, X. C. Ai +405

Using 482 pb $^{- 1}$ of data taken at $s = 4.009$ GeV, we measure the branching fractions of the decays of $D^{* 0}$ into $D^{0} π^{0}$ and $D^{0} γ$ to be $\BR(D^{*0} \to D^0π^0)=(65.5…
