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…

Study of $ϕ \to K K ˉ$ in the amplitude analysis of $D^{+} \to K_{S}^{0} K_{L}^{0} π^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +772

We present the first amplitude analysis and branching fraction measurement of $D^{+} \to K_{S}^{0} K_{L}^{0} π^{+}$ decay. The analysis uses a dataset corresponding to an int…

Spin-flavor entanglement in $Λ_{b} \to Λ D$ and weak phase extraction

Yong Du, Chao-Qiang Geng, Xiao-Gang He +3

We identify a new spin-flavor entanglement structure in $Λ_{b} \to Λ D$ decays, formed by the correlation between the $Λ$ spin and the $D$ flavor states ( $D = D^{0}, D^{0}, D_{1}, D_{2}$ ).…

Measurement of branching fractions of $D_{s}^{+} \to K_{S}^{0} K_{S}^{0} π^{+} π^{0}$ and $D_{s}^{+} \to K_{S}^{0} K^{+} π^{0} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +683

By analyzing $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 7.33~fb $^{- 1}$ collected with the BESIII detector at center-of-mass energies ranging from 4.128 to…
