Measurement of the hyperon weak radiative decay at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +615
The hyperon weak radiative decay is measured via the process . The absolute branching fraction of is determined to be $(3.69\pm 0.21_{\t…
Measurement of Born Cross Sections and Effective Form Factors of from = 3.7 to 4.7 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +635
Using collision data corresponding to an integrated luminosity of 22.7 fb, collected at center-of-mass energies between 3.7 and 4.7 GeV with the BESIII detector at…

Study of the tracking efficiency of charged pions at BESIII
Fang Liu, Xiao-Bin Ji, Sheng-Sen Sun +11
Using events collected with the BESIII detector in 2009, 2012, 2018 and 2019, the tracking efficiency of charged pions is studied using the decay…
