英文摘要	The gluon flux distribution of a static three quark system has been revealed at finite temperature in the pure SU(3) Yang-Mills theory. An action density operator is correlated with three Polyakov loops representing the baryonic state at temperatures near the end of the QCD plateau, T/T-c approximate to 0.8, and another just before the deconfinement point, T/T-c approximate to 0.9. The flux distributions at short distance separations between the quarks display an action-density profile consistent with a rounded filled delta shape iso surface. However the delta shape action iso-surface distributions are found to persist even at large interquark separations. The action density distribution in the quark plane exhibits a nonuniform pattern for all quark separations considered. This result contrasts with the Y-shaped uniform action density gluonic-flux profile obtained using the Wilson loop as a quark source operator at zero temperature. We systematically measure and compare the main aspects of the profile of the flux distribution at the two considered temperature scales for three sets of isosceles triangle quark configurations. In this paper, we present major characteristics of the gluonic profile including radii, amplitudes, and rate of change of the width of the flux distribution. These aspects show significant changes as the temperature changes from the end of the QCD plateau towards the deconfinement point. In particular, we found the flux tube is exhibiting a linear divergence at some planes of the gluonic pattern for the temperature close to the deconfinement point.
