Measurement of branching fractions of J/psi and psi(3686) decays to Sigma(+) and (Sigma)over-bar(-)

Ablikim, M.; Achasov, M. N.; Adlarson, P.; Ahmed, S.; Albrecht, M.; Aliberti, R.; Cetin, S. A.; Kolcu, O. B. (SPRINGER, 2021)

Using 1310.6 x 10(6) J/psi and 448.1 x 10(6) psi(3686) events collected with the BESIII detector, the branching fractions of J/psi decays to Sigma(+)(Sigma) over bar (-) is measured to be (10.61 +/- 0.04 +/- 0.36) x 10(-4), ...

Study of the processes chi(cJ) -> Xi(-)(Xi)over-bar(+) and Xi(0)(Xi)over-bar(0)

Ablikim, M.; Achasov, M. N.; Adlarson, P.; Ahmed, S.; Kolcu, Onur Bugra (SPRINGER, 2022)

Using 448.1 x 10(6) psi(3686) decays collected with the BESIII detector at the BEPCII e(+)e(-) storage rings, the branching fractions and angular distributions of the decays chi(cJ) -> Xi(-)(Xi) over bar (+) and Xi(0)(Xi) ...
