New high-statistics measurement of the $π^{0} \to e^{+} e^{-} γ$ Dalitz decay at the Mainz Microtron

S. Prakhov, L. Heijkenskjöld, S. Abt +69

The Dalitz decay $π^{0} \to e^{+} e^{-} γ$ has been measured with the highest statistical accuracy obtained so far in the $γ p \to π^{0} p$ reaction with the A2 tagged-photon facility at the M…

Model-independent extraction of form factors and $∣ V_{c b} ∣$ in $B \to D ℓ^{-} ν_{ℓ}$ with hadronic tagging at BaBar

BaBar Collaboration, J. P. Lees, V. Poireau +208

Using the entire BaBar $Υ (4 S)$ data set, the first two-dimensional unbinned angular analysis of the semileptonic decay $B \to D ℓ^{-} ν_{ℓ}$ is perfor…

Target and beam-target asymmetries for the $γ p \to π^{0} π^{0} p$ reaction

S. Garni, V. L. Kashevarov, A. Fix +81

Background: Photoproduction of pion pairs allows to study sequential decays of nucleon resonances via excited intermediate states. Such decays are important e.g. for states which i…

Study of the reactions $e^{+} e^{-} \to π^{+} π^{-} π^{0} π^{0} π^{0} π^{0}$ and $π^{+} π^{-} π^{0} π^{0} π^{0} η$ at center-of-mass energies from threshold to 4.5 GeV using initial-state radiation

BaBar Collaboration

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

Light meson spectroscopy from Dalitz plot analyses of $η_{c}$ decays to $η^{'} K^{+} K^{-}$ , $η^{'} π^{+} π^{-}$ , and $η π^{+} π^{-}$ produced in two-photon interactions

J. P. Lees

We study the processes $γ γ \to η_{c} \to η^{'} K^{+} K^{-}$ , $η^{'} π^{+} π^{-}$ , and $η π^{+} π^{-}$ using a data sample of 519 $f b^{- 1}$ recorded with the BaBar detector operating at the SLAC PEP-II a…

Search for lepton-flavor violating decays $D^{0} \to X^{0} e^{\pm} μ^{\mp}$

BaBar Collaboration, J. P. Lees, V. Poireau +238

We present a search for seven lepton-flavor-violating neutral charm decays of the type $D^{0} \to X^{0} e^{\pm} μ^{\mp}$ , where $X^{0}$ represents a $π^{0}$ , $K_{S}^{0}$ …
