Measurement of Σ + transverse polarization in e + e − collisions at s = 3. 68 − 3. 71 GeV
- Abstract:
- 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 Σ+ hyperon in the e+e− → Σ+Σ¯− reaction. At each energy point, no evident polarization is observed. These results are helpful to understand the production mechanism of the Σ+-Σ¯− pairs.
