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…

Observation of $I ¨ (3686) \to I^^{3} I^\cdot (1405)$ via $I^\cdot (1405) \to f_{0} (980) I ¨ ^{0}$

M. Ablikim, M. N. Achasov, P. Adlarson +694

The decay $I ¨ (3686) \to I^^{3} I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ is studied using a sample of $(2712.4 \pm 14.3) \times 1 0^{6}$ $I ¨ (3686)$ events collected with the BESIII detector. The decay $Î·(1405)\toÏ^+Ï^-Ï…

Search for sub-GeV invisible particles in inclusive decays of $J / I ¨ $ to $I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +696

A search for an invisible particle, $X$ , with a mass between 0 and 0.96 $GeV / c^{2}$ , is performed in the process $J / I ¨ \to I ¨ + X$ using $(8774.0\pm39.4)\tim…
