A better way to find hidden-charm pentaquarks in particle collisions

Hidden-charm pentaquarks—exotic five-quark particles—emerge from meson-baryon interactions, but standard calculation methods produce unphysical artifacts that obscure real predictions. This work introduces a hybrid loop function scheme that strips away these fake poles while preserving genuine states, successfully matching all six experimentally confirmed hidden-charm pentaquarks and forecasting new resonances in unexplored regions of quark flavor space.
