Measurements of the center-of-mass energies at BESⅢ via the di-muon process
|
摘要
From 2011 to 2014,the BESIII experiment collected about 5 fb~(-1) data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states.By analyzing the di-muon process e~+e~- → Yisr/fsr μ~+μ~-,the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV.The center-of-mass energy is found to be stable for most of the time during data taking.
