Color Screening from Flux Tube in (2 + 1)-Flavour QCD

In this study, we analyse the dependence of the penetration length and the effective mass, the flux tube width and the free energy on temperature and\(q\bar {q}\) separation. From the results of the non-vanishing penetration length and effective mass, we observe screening of the color electric field. The free energy exhibits that the screening phenomenon depends on interquark distance and temperature. For width of the flux tube, we observe quantum widening up to\(R = 1.5\) fm at all temperatures which are in close vicinity to the deconfinement transition temperature\({{T}_{{\text{c}}}}\).
