Description
The dynamics of the glueballs is important in the context of their experimental search as well as for understanding non-Abelian theories. The glueballs of the dark SU(N) Yang-Mills theory are also good candidates of the dark matter [1,2].
The low energy effective Lagrangian of the 0++ glueball may be determined from the interglueball potential calculated on lattice. In this talk, we report on the result of the lattice calculations of the interglueball potential of the Yang-Mills theory with the color numbers N=2,3,4, with a detailed inspection of the systematics due to the discretization.
