Description:
We report an observation of the process J/ψ→γX(1835)→γK0SK0Sη at low K0SK0S mass with a statistical significance larger than 12.9σ using a data sample of 1.31×109 J/ψ events collected with the BESIII

Description:
A measurement of the number of J/ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to

Description:
We report the first measurement of absolute hadronic branching fractions of Λ+c baryon at the Λ+cΛ¯−c production threshold, in the 30 years since the Λ+c discovery. In total, 12 Cabibbo-favored Λ+c ha

Description:
From December 2011 to May 2014, about 5 fb−1 of data were taken with the BESIII detector at center-of-mass energies between 3.810 GeV and 4.600 GeV to study the charmonium-like states and higher excit

Description:
We present a measurement of the azimuthal asymmetries of two charged pions in the inclusive process e+e−→ππX, based on a data set of 62 pb−1 at the center-of-mass energy of 3.65 GeV collected with th
