Measurement of ${\Sigma }^{+}$ transverse polarization in $e^{+}{e}^{-}$ collisions at $\sqrt{s}=3.68-3.71$ GeV

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

Using $e^{+}{e}^{-}$ collision data collected with the BESIII detector at seven energy points ranging from 3.68 to 3.71 GeV and corresponding to an integrated luminosity of $652.1~{\rm p…
