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 the decay $D^{0} \to K_{S}^{0} I ¨ ^{0} I ¨ ^{0}$

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

An amplitude analysis of the decay $D^{0} \to K_{S}^{0} I ¨ ^{0} I ¨ ^{0}$ is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^…
