Description
The observation of hidden-charm pentaquark states by the LHCb collaboration in 2015, as a result of amplitude analysis of $\Lambda_b^0 \rightarrow J/\psi p K^⁻$ decays, marked a significant breakthrough in exotic hadron spectroscopy. Independent confirmation of these states is now essential, alongside an assessment of how potential contributions from $Z_{cs}$ states might affect their significance. This work will review the methodology for studying pentaquark states via an amplitude analysis of $\Lambda_b^0 \rightarrow J/\psi p K^⁻$ decays with the ATLAS detector. Furthermore, it will discuss the prospects for their search in proton-proton collision data at a center-of-mass energy of $\sqrt{s}$ = 13 TeV.
