## Contribution

It provides a detailed analysis of the effects of absorptive corrections and nuclear form factors on dilepton production predictions at LHC energies.

## Key findings

- Good agreement with ALICE and ATLAS data for electron and muon pairs
- Assessment of different theoretical models for absorptive corrections

## Abstract

In this paper we perform a systematic study of the exclusive dilepton production by $\gamma \gamma$ interactions in $PbPb$ collisions at the LHC Run 2 energies considering different levels of precision for the treatment of the absorptive corrections and for the nuclear form factor. The rapidity and invariant mass distributions are estimated taking into account the experimental cutoffs and a comparison with the recent ALICE and ATLAS data for the $e^+ e^-$ and $\mu^+ \mu^-$ production is presented.
