Static three quark potential in the quenched lattice QCD

We study the static three quark potential using lattice QCD simulation. At zero temperature, the three quark potential is extracted from the baryonic Wilson loop and fitted to the phenomenological form, the sum of the Coulomb term, linearly rising term and the constant. We compare two types of the l inear term, "Y" and "Delta" type, and find that the string tension almost c oincide with sigma (Q (Q) over bar) the former case. We also investigate th e three quark potential at finite temperature using the Polyakov loop corre lation. In the deconfined phase, the screened potential is observed similar ly to the case of Q (Q) over bar system.
