Ablikim, M., Achasov, M. N., Ahmed, S., Ai, X. C., AlbayraK, O., Albrecht, M., . . . Collaboration, B. (2017). Measurement of integrated luminosity and center-of-mass energy of data taken by BESIII at root s=2.125 GeV. Chinese Physics C, 41(11), 9. doi:10.1088/1674-1137/41/11/113001Özet
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 Bhabha scattering events, the integrated luminosity of this data set is determined to be 108.49 +/- 0.02 +/- 0.85 pb(-1), where the first uncertainty is statistical and the second one is systematic. In addition, the center-of-mass energy of the data set is determined with radiative dimuon events to be 2126.55 +/- 0.03 +/- 0.85 MeV, where the first uncertainty is statistical and the second one is systematic.
