Observation of eta ' -> pi(+)pi(-)mu(+)mu(-)
(Amer Physical Soc., 2021)
Using (1310.6 +/- 7.0) x 10(6) J/psi events acquired with the BESIII detector at the BEPCII storage rings, the decay eta' -> pi(+)pi(-)mu(+)mu(-) is observed for the first time with a significance of 8 sigma via the process ...
Cross Sections for the Reactions e(+)e(-) -> K+ K- pi(+)pi(-) (x0), K+K-K+K- (pi(0)), pi(+)pi(-)pi(+)pi(-) (x(0)), pp over bar pi(+)pi(-) (pi(0)) in the Energy Region Between 3.773 and 4.600 GeV
(Amer Physical Soc., 2021)
Using the data samples collected in the energy range from 3.773 to 4.600 GeV with the BESIII detector at the BEPCII collider, we measure the dressed cross sections as a function of center-of-mass energy for e(+)e(-) -> ...
Study of e(+)e(-) -> pi X-0(3872)gamma and search for Z(c)(4020)(0) -> X(3872)gamma
(Amer Physical Soc., 2021)
Using data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of- mass energies from 4.178 to 4.600 GeV, we study the process e(+)e(-) pi X-0(3872)gamma and search for Z(c)(4020)(0) ...
Measurements of the Branching Fractions of psi(3686) -> (Sigma)over-bar(0)Lambda + c.c: and chi cJ(J=0,1,2) -> Lambda(Lambda)over-bar

Based on 4.481 x 10(8) psi(3686) events collected with the BESIII detector at BEPCII, the branching fraction of the isospin violating decay psi(3686)-> (Sigma) over bar0 Lambda+c.c: is measured to be (1.60 +/- 0.31 +/- ...
Search for New Decay Modes of the psi(2)(3823) and the Process e(+)e(-) -> pi(0)pi(0)psi(2) (3823)
(Amer Physical Soc., 2021)
The decays psi(2)(3823) -> gamma chi(c0,1,2), pi(+)pi(-) J/psi, pi 0 pi(0) J/psi, eta J/psi, and pi(0)J/psi are searched for using the reaction e(+)e(-) -> pi(+)pi(-)psi(2) (3823) in a 19 fb(-1) data sample collected at ...
Measurement of the e(+)e(-) -> pi(+)pi(-) Cross Section Between 600 and 900 MeV Using Initial State Radiation (vol 753, pg 629, 2016)
(Elsevier, 2021)
In Ref.[1] the BESIII collaboration published a cross section measurement of the process e(+)e(-) -> pi(+)pi(-) in the energy range between 600 and 900 MeV. In this corrigendum, we report a corrected evaluation of the ...
Measurement of the D -> K-pi(+)pi(+)pi(-) and D -> K-pi(+)pi(0) coherence factors and average strong-phase differences in quantum-correlated D(D)over-bar decays
