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…

First measurement using elliptically polarized photons of the double-polarization observable $E$ for $γ p \to p π^{0}$ and $γ p \to n π^{+}$

A2 Collaboration, F. Afzal, K. Spieker +74

We report the measurement of the helicity asymmetry $E$ for the $p π^{0}$ and $n π^{+}$ final states using, for the first time, an elliptically polarized photon beam in combination with…

Evaluation of the E2/M1 ratio in the $N \to Δ (1232)$ transition from the $γ p \to p π^{0}$ reaction

E. Mornacchi, P. Pedroni, F. Afzal +59

A new data set for the helicity-dependent differential cross section of the single-meson photoproduction reaction $γ p \to p π^{0}$ was obtained for the photon energy interval 150-4…

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…

Helicity dependent cross sections for the photoproduction of $π^{0} π^{\pm}$ pairs from quasi-free nucleons

A2 Collaboration, D. Ghosal, V. Sokhoyan +71

Photoproduction of $π^{0} π^{\pm}$ -pairs from quasifree nucleons bound in the deuteron has been investigated to study the helicity dependence of this reaction. Measurements with a liq…

Neutron polarisation transfer, $C_{x^{'}}^{n}$ , in $π^{+}$ photoproduction off the proton

M. Bashkanov, D. P. Watts, S. J. D. Kay +63

We report a first measurement of the double-polarisation observable, $C_{x^{'}}$ , in $π^{+}$ photoproduction off the proton. The $C_{x^{'}}$ double-polarisation observable represents the t…
