Using events collected by the Beijing Spectrum III (BESIII) detector at the Beijing Electron Positron Collider II (BEPCII) collider, we search for the hyperon semileptonic decay . No significant signal is observed and the ...

During the 2016-17 and 2018-19 running periods, the BESIII experiment collected 7.5 fb -1 of e+e- collision data at center-of-mass energies ranging from 4.13 to 4.44 GeV. These data samples are primarily used for the study ...

The singly Cabibbo suppressed decay Λc+→pη′ is measured using 4.5 fb-1 of e+e-collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. Evidence for Λc+→pη′ with a ...

Using data samples collected with the BESIII detector operating at the BEPCII storage ring, we measure the cross sections of the e+e-→π+π-D+D- process at center-of-mass energies from 4.190 to 4.946 GeV with a partial ...

The hadronic decay ηc(2S)→3(π+π-) is observed with a statistical significance of 9.3 standard deviations using (448.1±2.9)×106 ψ(3686) events collected by the BESIII detector at the BEPCII collider. The measured mass and ...

Based on 10 billion J/ψ events collected at the BESIII experiment, a search for CP violation in Λ decay is performed in the difference between CP-odd decay parameters α- for Λ→pπ- and α+ for Λ¯→p¯π+ by using the process ...

Using a data sample corresponding to an integrated luminosity of 11.3  fb^{-1} collected at center-of-mass energies from 4.23 to 4.70 GeV with the BESIII detector, we measure the product of the e^{+}e^{-}→π^{+}π^{-}ψ_{2}(3823) ...

We study the direct production of the JPC=1++ charmonium state χc1(1P) in electron-positron annihilation by carrying out an energy scan around the mass of the χc1(1P). The data were collected with the BESIII detector at ...

We study the processes e+e-→KS0Ds+D∗- and e+e-→KS0Ds∗+D-, as well as their charge conjugated processes, at five center-of-mass energies between 4.628 and 4.699 GeV, using data samples corresponding to an integrated luminosity ...

Using a sample of (10.09±0.04)×10^{9} J/ψ events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/ψ→γηη^{'} is performed. The first observation of an isoscalar ...
