Observation of a Near-Threshold Enhancement in the Lambda(Lambda)over-bar mass spectrum from e(+)e(-) -> phi Lambda(Lambda)over-bar at root S is from 3.51 to 4.60 GeV
(Amer Physical Soc., 2021)
The process e(+)e(-) -> phi Lambda(Lambda) over bar is studied using data samples collected with the BESIII detector at the BEPCII Collider at center of mass energies root S ranging from 3.51 GeV to 4.60 GeV. An enhancement ...
Model-independent determination of the relative strong-phase difference between D-0 and (D)over-bar(0) -> K-S,L(0)pi(+)pi(-) and its impact on the measurement of the CKM angle gamma/phi(3)
(Amer Physical Soc., 2020)
Crucial inputs for a variety of CP-violation studies can be determined through the analysis of pairs of quantum-entangled neutral D mesons, which are produced in the decay of the psi(3770) resonance. The relative strong-phase ...
Search for the Decay D-s(+) -> a(0)(980)(0)e(+)nu(e)
(Amer Physical Soc., 2021)
Using 6.32 fb(-1) of electron-positron collision data recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, we present the first search for the decay D-s(+) -> a(0)(980)(0)e(+)nu(e), ...
Measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X: (BESIII Collaboration)
(Springer, 2020)
We report the first measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X. The analysis is performed using an e+e- collision data sample corresponding to an integrated luminosity of 567 ...
Study of the process e(+) e(-) -> pi(0)pi(0)J/psi and neutral charmoniumlike state Z(c)(3900)(0)
