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 / I ¨ $ events at BESIII, the…

Amplitude analysis and branching fraction measurement of $J / I ¨ \to I^ I^ˉ £^{0} I^\cdot + c.c$

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

Based on a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector, a partial-wave analysis of $J / I ¨ \to I^ I^£ ˉ^{0} I^\cdot + c.c$ is performed f…

Observation and branching fraction measurements of $I ¨ _{c J} \to p p ˉ K_{S}^{0} K_{S}^{0}$

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

Based on $(2.712 \pm 0.014) \times 1 0^{9}$ $I ¨ (3686)$ events collected with the BESIII detector, the decays $I ¨ _{c J} \to p p ˉ K_{S}^{0} K_{S}^{0}$ ( $J = 0, 1, 2$ ) are observed for the f…
