Proof of principle for nucleon polarization measurement at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +754

A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using $10.09 \times 1 0^{9}$ $J / ψ$ events at BESIII, the…

Amplitude analysis and branching fraction measurement of $J / ψ \to Λ Σ ˉ^{0} η + c.c$

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

Based on a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, a partial-wave analysis of $J / ψ \to Λ Σ ˉ^{0} η + c.c$ is performed for th…

Cross section measurement of $e^{+} e^{-} \to π^{0} π^{0} ψ (3686)$ from $s =$ 4.008 GeV to 4.951 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +682

Using data samples with a total integrated luminosity of $22.1 f b^{- 1}$ at center-of-mass energies between 4.008 and 4.951~GeV collected with the BESIII detector, the cross sec…

Measurements of the branching fractions of $χ_{c J} \to 2 K^{+} 2 K^{-} ω$ and $ϕ K^{+} K^{-} ω$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +688

Using a data sample of $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, we report the first observation of th…

First Observation of $D^{0 (+)} \to K ˉ ω e^{+} ν_{e}$ and Determination of the Branching Fraction of $K ˉ_{1} (1270) \to K ˉ ω$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using 20.3~fb $^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at a center-of-mass energy of 3.773~GeV with the BESIII detector, we report the first observation of the semileptonic d…
