Advantages of exclusive γγproduction to probe high mass systems

Abstract

We recall that the exclusive production of high mass objects via γγfusion at the LHC is not strongly suppressed in comparison with inclusive γγfusion. Therefore it may be promising to study new objects produced by the γγsubprocess 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.
