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…

Measurement of the branching fraction of the decay $J / I ¨ \to p p ˉ I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

A high precision measurement of the branching fraction of the decay $J / I ¨ \to p p ˉ I^\cdot$ is performed using $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events recorded by the {BESIII} d…

Cross section measurement of $e^{+} e^{-} \to I^\cdot I ¨ (2 S)$ and search for $e^{+} e^{-} \to I^\cdot X ~ (3872)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

The energy-dependent cross section for $e^{+} e^{-} \to I^\cdot I ¨ (2 S)$ is measured at eighteen center of mass energies from 4.288 GeV to 4.951 GeV using the BESIII detector. Using the same da…

Measurement of Branching Fractions for $I^_{c}^{+} \to n K_{S}^{0} I ¨ ^{+}$ and $I^_{c}^{+} \to n K_{S}^{0} K^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

Based on 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated at center-of-mass energies between $4.600 GeV$ and $4.699 GeV$ with the BESIII detector, we me…
