Strings of diquark-quark (QQ)Q baryon before phase transition
arXiv:2002.07202 · doi:10.1103/PhysRevD.108.094502
Abstract
We explore the limit at which the effective baryonic Y-string model of the junction approaches the mesonic stringlike behavior. We calculate and compare the numerical values of the static potential and energy-density correlators of diquark-quark and quark-antiquark configurations. The gauge model is pure Yang-Mills lattice gauge theory at coupling and finite temperature. The diquark setup is approximated as two quarks confined within a sphere of radius fm. The lattice data of the potential and energy show that the string binding the diquark-quark configuration displays an identical behavior to the quark-antiquark confining string. However, with the temperature increase to a small enough neighborhood of the critical point , the gluonic similarities between the two systems do not manifest neither at short nor intermediate distance scales fm. The comparison between the potential and the second moment of the action-density correlators for both systems shows significant splitting. This suggests that subsisted baryonic decoupled states overlap with the mesonic spectrum. The baryonic junction's model for the potential and the profile returns a good fit to the numerical lattice data of the diquark-quark arrangement. However, near the critical point, the mesonic string displays large deviations compared to fits of the corresponding quark-antiquark data.
