Improved measurements of branching fractions for eta(c) -> phi phi and omega phi
(Amer Physical Soc., 2017)
Using (223.7 +/- 1.4) x 10(6) J / Psi events accumulated with the BESIII detector, we study eta(c) decays to phi phi and omega phi final states. The branching fraction of n(c) -> phi phi is measured to be Br(eta(c) -> phi ...
Observation of a cross-section enhancement near mass threshold in e(+)e(-) -> Lambda(Lambda)over-bar
(Amer Physical Soc., 2019)
The process e(+)e(-) -> Lambda(Lambda) over bar is studied using data samples at root s = 2.2324, 2.400, 2.800 and 3.080 GeV collected with the BESIII detector operating at the BEPCII collider. The Born cross section is ...
Measurement of the matrix elements for the decays eta' -> eta pi(+) pi(-) and eta' -> eta pi(0)pi(0)
(Amer Physical Soc., 2018)
Based on a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, the matrix elements for the decays eta' -> eta pi(+) pi(-) and eta' -> eta pi(0)pi(0) are determined using 351,016 eta' -> (eta -> gamma ...
Measurement of the absolute branching fraction of D*(s0) (2317)(+/-) -> pi D-0(s)+/-
(Amer Physical Soc., 2018)
The process e(+)e(-) -> D*D-+(s)*(s0) (2317)(-) + c.c. is observed for the first time with the data sample of 567 pb(-1) collected with the BESIII detector operating at the BEPCII collider at a center-of-mass energy root ...
Measurement of the absolute branching fraction of D+ › K¯ 0e +?e via K¯ 0 › ? 0? 0 *
(IOPscience, 2016)
By analyzing 2.93 fb-1 data collected at the center-of-mass energy ? s = 3.773 GeV with the BESIII detector, we measure the absolute branching fraction of the semileptonic decay D + › K¯ 0 e +?e to be B(D+ › K¯ 0 e +?e) = ...
Measurements of the branching fractions of the singly Cabibbo-suppressed decays D-0 -> omega eta, eta(()'())pi(0) and eta(()'())eta
(Amer Physical Soc., 2018)
By analyzing a data sample of 2.93 fb(-1) collected at root s = 3.773 GeV with the BESIII detector operated at the BEPCII storage rings, we measure the branching fractions B(D-0 -> omega eta) = (2.15 +/- 0.17(stat) +/- ...

Precision Measurement of the e(+)e(-) -> Lambda(+)(c)(Lambda)over-bar(c)(-) Cross Section Near Threshold
(Amer Physical Soc., 2018)
The cross section of the e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c) process is measured with unprecedented precision using data collected with the BESIII detector at root s = 4574.5, 4580.0, 4590.0 and 4599.5 MeV. ...
Measurement of the e+e- › ?+?- cross section between 600 and 900 MeV using initial state radiation
(Elsevier, 2016)
We extract the e+e-›?+?- cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb-1 taken at a center-of-mass energy ...
