A non-Abelian gauge theory describes the strong interactions among particles with the commutator of generators are nonzero. An [Formula: see text] gauge theory describes the interactions that lead to nuclear forces among particles. The Lagrangian density refers to fermions with color and flavor and the gauge field quanta implying gluons. The gauge theory is treated at finite temperature using the Thermo Field Dynamics (TFD). Using self-interaction of gluons, the Stefan–Boltzmann law and the Casimir effect are calculated at finite temperature. An appendix is attached to give a response of a massless quarks in gauge theory.
