Measurement of the absolute branching fraction of D+ › K¯ 0e +?e via K¯ 0 › ? 0? 0 *
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 absolute hadronic branching fractions of the ? + c baryon
(APS Physics, 2016)
Observation of pseudoscalar and tensor resonances in J/?›???
Based on a sample of (1310.6±10.5)×106 J/? events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/?›??? is performed in order to study the intermediate states. ...
Search for the weak decay ?'›K±?± and precise measurement of the branching fraction B(J/?›??')
We present the first search for the rare decay of ?' into K±?± in J/?›??', using a sample of 1.3×109 J/? events collected with the BESIII detector. No significant signal is observed, and the upper limit at the 90\% confidence ...

Measurement of the branching fraction for ?(3770) › ??c0
By analyzing a data set of 2.92fb-1 of e+e- collision data taken at s=3.773GeV and 106.41×106 ?(3686) decays taken at s=3.686GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the ...
Study of ? decays to the ?-?¯+ and ?(1385)±?¯(1385)± final states
We study the decays of the charmonium resonances J/? and ?(3686) to the final states ?-?¯+, ?(1385)±?¯(1385)± based on a single baryon tag method using data samples of (223.7±1.4)×106 J/? and (106.4±0.9)×106 ?(3686) events ...
Observation of e+e-›??c1,2e+e-›??c1,2 near s?s = 4.42 and 4.6 GeV
BEPC-BES. Based on data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s?>s> 4.4 GeV, the processes e+e-›??c1,2e+e-›??c1,2 are observed for the first time. With ...
Study of J/Psi -> p(p)over-bar phi at BESIII
Using a data sample of 1.31×109 J/? events accumulated with the BESIII detector, the decay J/?›pp¯? is studied via two decay modes, ?›KS0KL0 and ?›K+K-. The branching fraction of J/?›pp¯? is measured to be B(J/?›pp¯?)=[5 ...
