GRIBOV-80 Memorial Volume: Quantum Chromodynamics and Beyond
We assume that the diquark is an independent body which is under the influence
of two types of forces. One is due to the background meson cloud which is
represented by potential V =-α/r, where α = 23αs, αs being the strong coupling ...

integrated luminosity found that -15-70 and 4-30 clean signal events/year could
be obtained for the diquarkino and scalar diquark, respectively. These authors
calculated search limits of Mh ~ 0.9 TeV and MK ~ 0.0 TeV. The production of ...

Supersymmetry breaking arises from at least three differences between a diquark
and a quark (or antiquark): 1) they have different sizes; 2) they have different
masses; and 3) they have different spins. We briefly discuss these differences.

(5.21) is thus given entirely by (3/2g2)gp° □ Axial vector diquark masses are
given in Tab. 5.1 for various values of qi- In contrast to the scalar diquark the axial
vector diquark is only weakly bound. The electromagnetic vertex function for ...

Unitary Symmetry and Elementary Particles
a quark and diquark, we need the symmetric 36 diquark rather than the
antisymmetric 28. Because in the model, excited baryon states arise from quark
excitations, we keep the diquark in a 36 multiplet. Of course, any of the three
quarks may ...

The Quark Confinement Model of Hadrons
Therefore, the hypothesis arose [11] to approximate the three-quark structure of a
baryon by a quark-diquark system. In this case, we have only three lines of the
vertex of the interaction Lagrangian (baryon-l-quark-l-diquark). In the original ...

effective action and thereby a description of baryons as loosely-bound
quarkdiquark composites. This is the class of theories with a chiral symmetry

The models that we are mainly interested in are; l) Diquark model, 2) Popcorn
model8' and 3) Cluster decay model. In the diquark model, the diquark is
considered to be (effectively) a fundamental object and diquark pair production is
