| Popis: |
Utilizing a quark model characterized by parameters that effectively replicate the masses of ground state hadrons, we illustrate that (us) or (ds) diquarks exhibit greater compactness in comparison to (ud) diquarks. Concretely, the binding energy of the (us) diquark - defined as the diquark's mass minus the combined masses of its individual quarks - is found to be stronger than that of the (ud) diquark. This heightened attraction present in (us) diquarks could lead to enhanced production of Ξc/D particles in high-energy pp or ultrarelativistic heavy-ion collisions. |
