QCD light-cone sum rules computation of magnetic dipole, electric quadrupole, and magnetic octupole moments for Σ-type P_ψs pentaquarks, with quark-flavor decomposition and model discriminants.
Overlaps between Gaussian in-medium c-cbar wave functions and vacuum charmonium wave functions can reproduce LHC hadron ratios, implying in-medium pair sizes of about 0.85 fm (pp) and 0.55 fm (Pb-Pb compact part) and a mixed compact plus molecular X(3872).
Imposing the SU(3) flavor eigenstate condition on udsc c-bar pentaquarks in a constituent quark model yields two structures matching the masses of P_cs(4338) and P_cs(4459) plus two additional predicted states below the J/ψΛ threshold.
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.

Hadronisation of in-medium $c\bar c$ pairs to the exotic $X(3872)$
