Glueball Regge trajectories and the pomeron: a lattice study

Abstract:

We perform lattice calculations of the lightest J = 0,2,4,6 glueball masses in the D = 3 + 1 SU(3) gauge theory and extrapolate to the continuum limit. Assuming that these masses lie on linear Regge trajectories we find a leading glueball trajectory α(t) = 0.93(24) + 0.28(2)α′ Rt, where α′ R ≃ 0.9 GeV -2 is the slope of the usual mesonic Regge trajectory. This glueball trajectory has an intercept and slope similar to that...
