Diquark properties from lattice QCD
read the original abstract
It has been argued recently that diquarks, a pair of quarks in the anti-triplet representation of SU(3) color, are important building blocks of baryons. The assumption that the scalar diquark is tightly bound seems to be nicely accommodated by experimental data. In this paper I attempt to extract phenomenological properties of diquarks from lattice QCD calculations. In particular, I use the MILC 2+1 dynamical fermion lattices with domain wall fermion valence quarks to probe diquarks very close to the chiral limit.

Scalar diquark mass and quark--diquark potential from lattice QCD using the potential method with a static quark
Using lattice QCD, the scalar diquark mass is found to be close to (2/3) of the nucleon mass, and the quark-diquark potential is of Cornell type with string tension agreeing to within 5% of the static quark-antiquark ...
