Contribution

It introduces a novel approach to reconstruct collision geometry in heavy ion interactions using forward proton detectors at the LHC.

Findings

Signals in forward detectors are sensitive to collision geometry.

A new impact parameter reconstruction method is proposed.

Monte Carlo simulations demonstrate the method's effectiveness.

Abstract

A possible use of forward proton tagging detectors at the LHC in the context of heavy ion interactions is discussed. It is shown that signals registered in such detectors are sensitive to the geometry of the collision. A method of the impact parameter and the collision asymmetry reconstruction on the event-by-event basis is proposed and its performance is studied with Monte Carlo simulations.
