Pentaquark states with hidden charm were discovered by the LHCb collaboration as a result of the analysis of *L&sup(0) &sub(b) *> J/*qpK&sup(−) decays in pp collision data with a center-of-mass energy of *%s =7.8 TeV. The study of the spectrum of these states was subsequently conducted both by the LHCb experiment using pp collision data with *%s = 13 TeV and by the ATLAS experiment using pp collision data with *%s =7.8 TeV. Current and future studies of *L&sup(0) &sub(b) *> J/*qpK&sup(−) decays are aimed at further investigation of the properties of the narrow resonances P&sub(cc)(4312)&sup(+), P&sub(cc)(4440)&sup(+), P&sub(cc)(4457)&sup(+). At the same time, the existence of the broad resonance P&sub(cc)(4380)&sup(+) remains in question, as does the potential contribution to *L&sup(0) &sub(b) *> J/*qpK&sup(−) decays from the strange tetraquark states T&sub(ccs1)(4000) and T&sub(ccs1)(4220). This paper presents a review of modern experimental results and the general methodology for analyzing *L&sup(0) &sub(b) *> J/*qpK&sup(−) decays at the ATLAS setup; it discusses the prospects for further experimental studies of pentaquark states in pp collision data with a center-of-mass energy of *%s = 13 TeV.
