Strong Coupling Expansion of Gluodynamics on a Lattice under Rotation

The analytic strong coupling expansion of the gluodynamics under a rotation with an angular velocity ω is reported. While the expansion is systematic, free from additional assumptions, the deconfinement temperature determined by the onset of the Polyakov loop expectation value decreases with the angular velocity up to ω², opposite to the tendency found in numerical simulations. As a by-product, a simple formula is obtained for the ω² coefficient of the deconfinement temperature shift in terms of the latent heat and the discontinuity of the moment of inertia at the transition without rotation. This formula is independent of the strong coupling and may benefit further investigation of the subject.
