Measurements of Sigma(+) and Sigma(-) time-like electromagnetic form factors for center-of-mass energies from 2.3864 to 3.0200 GeV
(Elsevier, 2021)
The Born cross sections of the e(+)e(-) -> Sigma(+)(Sigma) over bar (-) and e(+)e(-)-> Sigma(-)(Sigma) over bar (+) processes are determined for centerof-mass energy from 2.3864 to 3.0200 GeV with the BESIII detector. The ...
Observation of the Doubly Cabibbo-Suppressed Decay D+ -> K+ pi(+) pi(-) pi(0) and Evidence for D+ -> K+ omega
(Amer Physical Soc., 2020)
Using 2.93 fb(-1) of e(+)e(-) collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, the first observation of the doubly Cabibbo-suppressed decay D+-> K+pi(+)pi(-)pi(0) is reported. After ...
Model-Independent Determination of the Spin of the Omega(-) and Its Polarization Alignment in psi(3686) -> Omega(-)(Omega)over-bar(+)
(Amer Physical Soc., 2021)
We present an analysis of the process psi(3686) -> Omega(-)(Omega) over bar (+)(Omega(-). K-Lambda, (Omega) over bar (+) K+ (Lambda) over bar,(Omega) over bar (+) Lambda -> p pi(-), (Lambda) over bar -> p (p) over bar ...
Measurement of cross sections for e(+) e(-) -> mu(+) mu(-) at center-of-mass energies from 3.80 to 4.60 GeV
(Amer Physical Soc., 2020)
The observed cross sections for e(+)e(-) -> mu(+) mu(-) at energies from 3.8 to 4.6 GeVare measured using data samples taken with the BESIII detector operated at the BEPCII collider. We measure the muonic widths and determine ...
Study of BESIII Trigger Efficiencies with the 2018 J/psi Data
(2021)
Using a dedicated data sample taken in 2018 on the J/psi peak, we perform a detailed study of the trigger efficiencies of the BESIII detector. The efficiencies are determined from three representative physics processes, ...
