Search for the Rare Semi-leptonic Decay J/psi -> D(-)e(+)nu(e) + c.c.
(Springer, 2021)
Using 10.1 x 10(9)J/ events produced by the Beijing Electron Positron Collider (BEPCII) at a center-of-mass energy s = 3.097 GeV and collected with the BESIII detector, we present a search for the rare semi-leptonic decay ...
Measurements of Absolute Branching Fractions of Fourteen Exclusive Hadronic D Decays to eta
(Amer Physical Soc., 2020)
Using 2.93 fb(-1) of e(+)e(-) collision data taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first measurements of the absolute branching fractions of 14 hadronic D0(+) decays to ...
Measurement of Cross Section for e(+)e(-) -> Xi(-)(Xi)over-bar(+) Near Threshold at BESIII
(Amer Physical Soc., 2021)
The Born cross sections and effective form factors for process e(+)e(-) -> Xi(-)(Xi) over bar (+) are measured at eight center-of-mass energies between 2.644 and 3.080 GeV, using a total integrated luminosity of 363.9 pb(-1 ...
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)
(Amer Physical Soc., 2020)
Cross sections of the process e(+)e(-) -> pi(0)pi(0)J/psi at center-of-mass energies between 3.808 and 4.600 GeV are measured with high precision by using 12.4 fb(-1) of data samples collected with the BESIII detector ...
Observation of D-0 -> K-1 (1270) (-)e(+)nu(e)
(Amer Physical Soc., 2021)
Using 2.93 fb(-1) of e(+)e(-) collision data taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, the observation of the D-0 -> K-1 (1270)(-)e(+)nu(e) semileptonic decay is presented. The statistical ...
Search for the Lepton Number Violating Decay Sigma(-) -> pe(-) e(-) and the Rare Inclusive Decay Sigma(-) -> Sigma(+) X

Using a data sample of (1310.6 +/- 7.0) x 10(6) J/psi events taken with the BESIII detector at the center-of-mass energy of 3.097 GeV, we search for the first time for the lepton number violating decay Sigma(-) -> pe(-) ...
