Measurement of Σ<SUP>+</SUP> transverse polarization in <i>e</i><SUP>+</SUP><i>e</i><SUP>-</SUP> ecollisions at √<i>s</i>=3.68-3.71 GeV

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 pb(-1), we present an energy-dependent measurement of the transverse polarization, relative phase and modulus ratio of the electromagnetic form factors of the Sigma(+) hyperon in the e(+)e(-) -> Sigma(+)(Sigma) over bar (-) reaction. At each energy point, no evident polarization is observed. These results are helpful to understand the production mechanism of the Sigma(+)-(Sigma) over bar (-) pairs.
