Observation of gamma-gamma to gamma-Z events provides unique insights.

Abstract

We recall that the exclusive production of high mass objects via \gamma\gamma fusion at the LHC is not strongly suppressed in comparison with inclusive \gamma\gamma fusion. Therefore it may be promising to study new objects produced by the \gamma\gamma subprocess in experiments with exclusive kinematics. We list the main advantages of exclusive experiments. We discuss the special advantage of observing $\gamma\gamma \to X \to \gamma Z$ exclusive events.
