Dynamics of Glue-Balls in N=1 SYM Theory
arXiv:hep-th/0310050
Abstract
The extension of the Veneziano-Yankielowicz effective Lagrangian with terms including covariant derivatives is discussed. This extension is important to understand glue-ball dynamics of the theory. Though the superpotential remains unchanged, the physical spectrum exhibits completely new properties.
