Determination of the number of J/psi events with inclusive J/psi decays
(Chinese Physical, 2017)A measurement of the number of J/psi events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/psi. The number of J/psi events taken in 2009 is recalculated to be (223.7 +/- ... -
Luminosity measurements for the R scan experiment at BESIII
(Chinese Physical, 2017)By analyzing the large-angle Bhabha scattering events e(+)e(-) -> (gamma)e(+)e(-) and diphoton events e(+)e(-) -> (gamma)gamma gamma for the data sets collected at center-of-mass (c.m.) energies between 2.2324 and 4.5900 ... -
Measurement of integrated luminosity and center-of-mass energy of data taken by BESIII at root s=2.125 GeV
(Chinese Physical, 2017)To study the nature of the state Y (2175), a dedicated data set of e(+)e(-) collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analyzing large-angle ...
