Description

We look for the signature of the confining Y-bosonic string in the gluonic profile due to a system of three static quarks on the lattice. The gluonic distribution is calculated in pure Yang-Mills lattice gauge theory at finite temperature with Polyakov loops operators. The analysis of the action density unveils a background of a filled-$\mathrm{\Delta }$ distribution. However, we found an underlying structure of three string-like configuration that interpolates from $\mathrm{\Delta }$ to a $Y$-configurations; all within the $\mathrm{\Delta }$-shaped background. The length of the revealed Y-string-like distribution is maximum near the deconfinment point. The action density width profile returns good fits to a baryonic string model only for large quark separation. The Y-string configurations provides good fits for both the in-plane and off-plane width profile.
