abstract
It is plausible that several of the most profound aspects of low-energy QCD dynamics are connected to diquark correlations, including: paucity of exotics (which is the foundation of the quark model and of traditional nuclear physics), similarity of mesons and baryons, color superconductivity at high density, hyperfine splittings, $\Delta I = 1/2$ rule, and some striking features of structure and fragmentation functions. After a brief overview of these issues, I discuss how diquarks can be studied in isolation, both phenomenologically and numerically, and present approximate mass differences for diquarks with different quantum numbers. The mass-loaded generalization of the Chew-Frautschi formula provides an essential tool.

Quark model of nucleon based on an analogy with polaron
Mapping polaron physics onto quark-pion interactions gives a mass formula that reproduces the nucleon mass, but the central input is one third of that same nucleon mass.

Quark-diquark effective mass formalism for heavy baryon spectroscopy
A quark-diquark formalism extracts effective masses and couplings from known heavy baryon data to predict spectra across singly, doubly, and triply heavy sectors with two scenarios and a mass-dependent binding term.

Continuity from neutron matter to two-flavor quark matter with $^1 S_0$ and $^3 P_2$ superfluidity
The paper proposes that neutron 1S0 and 3P2 superfluidity map continuously to scalar and 3P2 d-quark pairing in a 2SC+⟨dd⟩ quark matter phase, extending quark-hadron continuity to two flavors.

Hyperon electromagnetic timelike elastic form factors at large $q^2$
Using a quark model calibrated in the spacelike region plus analyticity relations, the paper predicts timelike hyperon form factors that agree broadly with available data, with clear exceptions for Lambda and Xi-zero,...

$\lambda$, $\rho$, and $\sigma$ Regge trajectories for the hexaquark ${(\bar{u}(cc))(b(\bar{b}\bar{b}))}$ in the triquark-antitriquark picture
Derives λ, ρ1, ρ2, σ1, and σ2 Regge trajectories for the hexaquark (ū(cc))(b(b̄b̄)) in the triquark-antitriquark picture, showing substructure is required for most series and giving rough mass estimates for excited states.

Mass spectrum, magnetic moments and Regge trajectories of $\Omega_{ccb}$ and $\Omega_{cbb}$ baryons in the nonrelativistic quark--diquark model
In a nonrelativistic quark-diquark model fitted to B_c meson data, the authors predict ground-state masses of ~8.0 GeV for Ω_ccb and ~11.0 GeV for Ω_cbb along with magnetic moments and Regge trajectories for different...
