Ablikim, M., Achasov, M. N., Adlarson, P., Ahmed, S., Albrecht, M., Amoroso, A., ... & BESIII Collaboration. (2020). Study of BESIII Trigger Efficiencies with the 2018$ J/\psi $ Data. arXiv preprint arXiv:2009.11566.Özet
Using a dedicated data sample taken in 2018 on the J/psi peak, we perform a detailed study of the trigger efficiencies of the BESIII detector. The efficiencies are determined from three representative physics processes, namely Bhabha scattering, dimuon production and generic hadronic events with charged particles. The combined efficiency of all active triggers approaches 100% in most cases, with uncertainties small enough not to affect most physics analyses.
