Description
The chromomagneto monopoles, an excitation of the non-Abelian gauge field that carries chromomagnetic charge, are believed to be important in explaining confinement in vacuum and the strong coupling nature around the confinement-deconfinement transition temperature ($T_c$). The chromomagneto monopoles have been found to be a solution to the long-standing puzzle that one cannot simultaneously describe the experimental results of the nuclear modification factor ($R_{\mathrm{AA}}$) and elliptic flow ($v_2$) of high-energy particles. Yet, the fraction of chromomagneto monopoles is not precisely known from a theoretical perspective, and we extract its temperature-dependent fraction using Bayesian inference in this work. Our analysis, based on the \textsc{cujet3.1} modeling of the energetic hadrons' $R_{\mathrm{AA}}$ and $v_2$, indicates that the chromomagneto monopole is a significant constituent of the strongly interacting medium near $T_c$, and its contribution remains non-negligible at high temperatures $T\sim3\,T_c$. With the extracted chromomagneto fraction, our model yields good agreement with not only the experimental data for energetic hadrons, but also with the state-of-the-art knowledge of the heavy flavor diffusion parameter and the ratio between shear viscosity and entropy.
