Description
In the last few years many exotic hadrons, which are states which do not appear to fit with the expectations for an ordinary $q\bar{q}$ or $qqq$ hadrons in the quark model, have been observed at various experimental facilities. Such results have motivated a series of studies focused on the description of the internal structure of the exotic hadrons as well as the proposition of new channels to search and constrain the properties of these states. In particular, the study of hidden - heavy quark pentaquarks and fully heavy tetraquark states have received a lot of attention. In this contribution, I will present an overview of the recent results obtained by our group that demonstrated that the pentaquark states $P_c$ and $P_b$ as well as the fully - heavy tetracharm states $T_{4c}$ can be probed in photon - induced interactions at the LHC. In particular, these studies indicate that the study of $\gamma h$ and $\gamma \gamma$ interactions at LHC can also provide complementary and independent checks on the properties of exotic states, and help to understand their underlying nature.
