Abstract :
[en] The mass spectrum of pure (SUSY) Yang-Mills theory in 3 + 1 dimensions is discussed for an arbitrary simple gauge algebra within a quasigluon picture. The general structure of the low-lying gluelump and glueball spectrum is shown to be common to all algebras, excepted the lightest C = - glueballs that only exist when the gauge algebra is Ar=2 , that is in particular su(N > 2). In the case of N = 1 SUSY Yang-Mills, the lowest-lying gluinoball is found lighter than the lightest glueball. The shape of the static energy between adjoint sources is also discussed assuming the Casimir scaling hypothesis; it appears to be gauge algebra-dependent when at least three sources are considered. Finally, the obtained results are shown to be consistent with existing lattice data in the particular case of an su(N ) gauge algebra.
