ND experiment


Neutral Detector is a detector for particle physics experiments created by the team of physicists in the
Budker Institute of Nuclear Physics, Novosibirsk, Russia.
Experiments with the ND were conducted from 1982 to 1987 at the e+e− storage ring VEPP-2M in the energy range 2E=0.5-1.4 GeV.

Physics

At the beginning of 80s the leading cross sections of the electron-positron annihilation in the final states with charged particles were measured in the energy range 2E=0.5-1.4 GeV. Processes with the neutral particles in the final state were less studied. To investigate the radiative decays of the,, and mesons and other processes involving photons,, and mesons the ND
was constructed. Its distinguishing features are defined by the specially designed electromagnetic calorimeter based on NaI scintillation counters.
List of published analyses
Based on goals of the physics program the ND consist of
Electromagnetic calorimeter
Charged particle coordinate system
Flat coordinate 2-d wire proportional chambers
Iron absorber & anti-coincidence counters
collected with the ND experiment corresponds to the integrated luminosity 19 pb−1.
Results of the experiments with ND are presented in Ref.,
and are included in the PDG Review.
