Measurement of the branching fraction and $C P$ asymmetry in $B^{+} \to J / ψ ρ^{+}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +844

The branching fraction and direct $C P$ asymmetry of the decay $B^{+} \to J / ψ ρ^{+}$ are measured using proton-proton collision data collected with the LHCb detector at cent…

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 $ρ^{0}$ , $ω$ ,…

Search for the rare decay $B^{+} \to μ^{+} μ^{-} μ^{+} ν_{μ}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +844

A search for the rare leptonic decay $B^{+} \to μ^{+} μ^{-} μ^{+} ν_{μ}$ is performed using proton-proton collision data corresponding to an integrated luminosity of $4.7$ fb$…

Lepton Flavor Universality tests in $b \to s ℓ^{+} ℓ^{-}$ decays at LHCb

Biplab Dey

The electroweak sector of the Standard Model contains three generations of charged leptons $ℓ^{-} \in {e^{-}, μ^{-}, τ^{-}}$ as exact replicas of each other, except for their Yukawa coupl…

Observation of two resonances in the $Λ_{b}^{0} π^{\pm}$ systems and precise measurement of $Σ_{b}^{\pm}$ and $Σ_{b}^{*\pm}$ properties

LHCb collaboration, R. Aaij, C. Abellán Beteta +837

The first observation of two structures consistent with resonances in the final states $Λ_{b}^{0} π^{-}$ and $Λ_{b}^{0} π^{+}$ is reported using samples of $pp$ collision data collected by the…

Study of the reactions $e^{+} e^{-} \to π^{+} π^{-} π^{0} π^{0} π^{0} γ$ and $π^{+} π^{-} π^{0} π^{0} η γ$ at center-of-mass energies from threshold to 4.35 GeV using initial-state radiation

J. P. Lees

We study the processes $e^{+} e^{-} \to π^{+} π^{-} π^{0} π^{0} π^{0} γ$ and $π^{+} π^{-} π^{0} π^{0} η γ$ in which an energetic photon is radiated from the initial state. The data were collected with the BaBar~ det…
