Deciphering the nature of $P^{\Sigma}_{\psi s}$ pentaquarks in the light of their electromagnetic multipole moments
Electromagnetic moments of Σ-type pentaquarks are computed via light-cone sum rules, yielding flavor-sensitive magnetic dipoles, quadrupoles, and octupoles that distinguish diquark types and rule out S-wave molecules.
