Study of the process e(+)e(-) -> phi eta at center-of-mass energies between 2.00 and 3.08 GeV

Ablikim, M.; Achasov, M. N.; Adlarson, P.; Ahmed, S.; Albrecht, M.; Aliberti, R.; Amoroso, A.; Kolcu, Onur Bugra (2021)

The process e(+)e(-) -> phi eta is studied at 22 center-of-mass energy points (root s) between 2.00 and 3.08 GeV using 715 pb(-1) of data collected with the BESIII detector. The measured Born cross section of e(+)e(-) -> ...

Observation of chi(cJ) -> lambda(lambda)over-bar(eta)

Ablikim, M.; Achasov, M. N.; Adlarson, P.; Albrecht, M.; Aliberti, R.; Cetin, Serkant Ali; Kolcu, Onur Bugra (PHYSICAL REVIEW D, 2022)

By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(cJ) -> Lambda(Lambda) over bar (eta) (J = 0, 1, and 2) are observed for the first ...
