On a \(Z^{\prime}\) signature at next high energy electron-positron colliders

The associated production of a \(Z^{\prime}\) and a final hard photon in high energy electron-positron colliders is studied. It is shown that the hard-photon spectrum contains useful information on the \(Z^{\prime}\) properties. This suggests that, if a new neutral gauge boson exists for \(M_{Z^{\pr...

Summary:The associated production of a \(Z^{\prime}\) and a final hard photon in high energy electron-positron colliders is studied. It is shown that the hard-photon spectrum contains useful information on the \(Z^{\prime}\) properties. This suggests that, if a new neutral gauge boson exists for \(M_{Z^{\prime}} < \sqrt{s}\), it will not be necessary to make a new energy run at the \(Z^{\prime}\) mass in order to get most of its properties.
