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.

Strange hidden-charm pentaquarks modeled as diquark-triquark bound states yield masses between 4200-4590 MeV for S-waves, with P_c cs(4459) assigned as a 3/2- state and P_c cs(4338) as a 1/2- state, plus a predicted lowest 1/2- state at 4200 MeV.
Fully heavy pentaquark fragmentation functions PQ5Q1.0 are completed for charm and bottom flavors and used to compute NLL/NLO+ semi-inclusive production rates at future colliders.
This review summarizes the historical motivation, detector design, experimental techniques, and major physics results of the LHCb experiment at the LHC.
