Evidence for the decays of Lambda(+)(C) -> Sigma(+) eta and Sigma(+) eta '
(IOP PUBLISHING LTD, 2019)
We study the hadronic decays of Lambda(+)(C) to the final states Sigma(+) eta and Sigma(+) eta', using an e(+) e(-) annihilation data sample of 567 pb(-1) taken at a center-of-mass energy of 4.6 GeV with the BESIII detector ...
Measurement of the phase between strong and electromagnetic amplitudes of J/Psi decays
(Elsevier Science, 2019)
Using 16 energy points of e(+) e(-) annihilation data collected in the vicinity of the J/Psi resonance with the BESIII detector and with a total integrated luminosity of around 100 pb(-1), we study the relative phase between ...
Study of the Dalitz decay J/psi -> e(+)e(-)eta
(Amer Physic Soc., 2019)
We study the electromagnetic Dalitz decay J/psi -> e(+)e(-)eta and search for dielectron decays of a dark gauge boson (gamma') in J/psi -> gamma'eta with the two q decay modes eta -> gamma gamma and eta -> pi(+)pi(-)pi(0) ...
Observation of h(1)(1380) in the J/psi -> eta ' K(K)over-bar pi decay
(Amer Physical Soc., 2018)
Using 1.31 x 10(9) J/psi events collected by the BESIII detector at the BEPCII e(+)e(-) collider, we report the first observation of the h(1)(1380) in J/psi -> eta'h(1)(1380) with a significance of more than ten standard ...
Search for the rare decay of Psi(3686) -> Lambda+pe(+)e(-) +c.c. at BESIII
(Amer Physical Soc., 2018)
Based on a data sample of (448.1 +/- 2.9) x 10(6)Psi(3686) decays collected with the BESIII experiment, a search for the flavor changing neutral current transition Psi(3686) -> Lambda(+)(c) pe(+) e(-) + c.c. is performed ...
Observation of chi(cJ) -> 4K(S)(0)
(Amer Physic Soc., 2019)
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(c)(J) -> 4K(S)(0) (J = 0, 1, 2) are observed for the first time with statistical ...
Measurement of the Absolute Branching Fraction of the Inclusive Semileptonic Lambda(+)(c) Decay
(Amer Physical Soc., 2018)
Using a data sample of e(+)e(-) collisions corresponding to an integrated luminosity of 567 pb(-1) collected at a center-of-mass energy of root s = 4.6 GeV with the BESIII detector, we measure the absolute branching fraction ...

Using a data sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider, we report the first observation of the electromagnetic Dalitz decay psi(3686) -> eta'e(+)e(-), with significances ...
Partial-wave analysis of J /? ?k+K-?0
(American Physical Society, 2019)
A partial-wave analysis of the decay J/??K+K-?0 has been made using (223.7±1.4)×106 J/? events collected with the BESIII detector in 2009. The analysis, which is performed within the isobar-model approach, reveals contributions ...
